Given:

The hundreds digit of a three-digit number = 7 + units digit.

Concept:

Place value: The digit of any number is called its place value.

For example, in the number 256, the place value of 5 is 5.

Face value: It is the actual value of any digit in a particular number.

For example, in the number 256, the face value of 5 is 50.

Any number can be written as the sum of, a product of the face value and place value.

for three digit number, 

abc = 100a + 10b + c

Calculation:

Let the three-digit number is 'abc'

according to question,

a = 7 + c    

⇒ a - c = 7       .......(1)

Now, according to above discussion 'abc' can be written as,

abc = 100a + 10b + c    ......(2)

on reversing the number, we get the new number 'cba'

⇒ cba = 100c + 10b + a      ......(3)

Substracting equation (2) from (1)

abc - cba = ( 100a + 10b + c ) - ( 100c + 10b + a ) 

abc - cba = 99( a - c )

abc - cba = 99 × 7 = 693     [ from equation (1) ]

Hence, unit digit of final number will be 3.

Correct option is D) surgery

2. Did Rama paint this picture?

3. Columbus discovered America in 1492.

4. She went to her village last month.

5. The peon did not ring the bell in time

6. The fool didn’t learn from experience.

Calculation:

Let the two consecutive even number be x and x + 2

Now, A/Q

(x + 2)² – x² = 84

⇒ x² + 4 + 4x – x² = 84

⇒ 4x = 80

⇒ x = 20

The two consecutive number are 20 and 22

Sum = 20 + 22 = 42

∴ The sum of two consecutive even number is 42

• Status Quo Trap - This is the tendency to maintain things as they are, even when that may be significantly less than optimal. It's dangerous in cultures/organizations where sins of commission are punished more than sins of omission.
• Sunk cost Trap - It refers to a tendency for people to irrationally follow through on an activity that is not meeting their expectations. This is because of the time and/or money they have already invested.
• Prudence Trap - The overconfidence trap refers to the tendency that individuals overestimate their ability to predict future events. The prudence trap takes the form of overcautiousness, or prudence: When faced with high-stakes decisions, we tend to adjust our estimates or forecasts “just to be on the safe side”.
• Anchoring Trap - Anchoring can occur when an individual or group latches onto the first information they encounter about a decision. A leader of a group may unintentionally anchor a group's thinking by presenting their opinion or analysis first in a decision-making process.
• Loss Aversion Bias - It is a cognitive phenomenon where a person would be affected more by the loss than by the gain i.e., in economic terms the fear of losing money is greater than gaining money more than the amount that might be lost so therefore, a bias is present to averse the loss first.

Trick to find square root of a number.

Method and Calculation:-

 • Find the unit digit of square root by looking at unit digit of given number.

For √17161, unit digit must be 9 or 1

 • Find other two digits by looking at number formed by first 3 digit.

169 < 171 < 196 (169 and 196 are squares of 13 and 14, so remaining part of square root will be 13.

 • Find the square root from the narrowed down options.

√17161 = 131 or 139. To find this, we multiply 13 × 14, which is equal to 182 and is more than 171. Hence the smaller of two will be the square root

Clearly, √17161 = 131

Correct option: c. 20^o

The entrepreneurs who are technical by nature in the sense of having the capability of developing new and improved quality of goods and services out of their own knowledge, skill and specialization are called a technical entrepreneur. They are essentially compared to craftsmen who concentrate more on production than marketing.

Most of the communication that we relay to others is done through our body language. If we have a negative body language when we interact with others it can show our lack of care. Two of the most important aspects of positive body language are smiling and eye contact. Make sure to look your customers in the eye. It shows that we are listening to them. And then of course, smiling makes the conversion more positive.

i) Tyre pressure monitoring systems: Tyre pressure monitoring systems provide the latest and greatest technology for eliminating low tyre pressure on our cars, which can result in an accident or simply poor gas mileage. A tire pressure monitoring system can also alert us in seconds to a flat tyre, thereby reducing the chances of becoming involved in a car accident due to a flat tyre. 

ii) Sensitive air bag systems: In older model cars, the airbag deploys when a front-end crash occurs. However, many of today’s vehicles come equipped with more sensitive air bag systems, which sense the difference in the size and weight of the occupants and deploys the air bags accordingly. This technology may even be able to detect that an individual is not wearing a seat belt or that he or she is positioned abnormally in the seat and compensate the air bag deployment to accommodate this.

Top five best new innovations in cars safety technology are as under: 

1. Tyre pressure monitoring systems: Tyre pressure monitoring systems provide the latest and greatest technology for eliminating low tyre pressure on our cars, which can result in an accident or simply poor gas mileage. A tire pressure monitoring system can also alert us in seconds to a flat tyre, thereby reducing the chances of becoming involved in a car accident due to a flat tyre. 

2. Blind-spot detection: Finally! There now is a system for alerting us if we attempt to make a turn and an object or car is in our blind spot. This technology responds as soon as the driver puts on the turn signal, thereby preventing a collision caused by the driver’s blind spot. 

3. Rollover prevention: Most of the newer SUVs are equipped with electronic stability control systems, but rollover prevention systems take the concept one stepfurther. If you are making a turn too fast and the car senses a potential rollover, the rollover Prevention system will apply the brakes and modulate the throttle as needed to help you maintain control of the vehicle. Ford calls it Roll Stability Control, while GM calls it Proactive Roll Avoidance. 

4. Sensitive air bag systems: In older model cars, the airbag deploys when a front-end crash occurs. However, many of today’s vehicles come equipped with more sensitive air bag systems, which sense the difference in the size and weight of the occupants and deploys the air bags accordingly. This technology may even be able to detect that an individual is not wearing a seat belt or that he or she is positioned abnormally in the seat and compensate the air bag deployment to accommodate this. 

5. Night vision assist: Properly operating a vehicle takes on a whole new meaning during the night time hours. Some of the newest vehicle technology allows drivers to see further down the road, courtesy thermal-imaging cameras, thereby allowing them to spot animals, pedestrians and other vehicles that they normally would not have seen

As we know that the probability of an impossible event is always zero because that event can never occur.

i.e., P(E) = 0 → (1)

Complement of any event is the event that is exactly opposite to that event. So, the complement of impossible events are the possible events.

As we know that the probability of an impossible event is always zero because that event can never occur. Complement of any event is the event that is exactly opposite to that event. So, the complement of impossible events are the possible events. Here, the complement of event E is denoted by event E'.

Trick to find cube root of a number.

Method and Calculation:-

 • Find the unit digit of cube root by looking at unit digit of given number.

For cube root of 10648, unit digit must be 2 (2³ is 8)

 • Find other digit(s) by ignoring the last three digits of number and looking at remaining digits.

8 < 10 < 27 (8 and 27 are cubes of 2 and 3, so remaining part of cube root will be 2)

Hence, 22 is our answer.

Deforestation and pollution.

a) Direct Current (DC)

b) Step 1: Apply acidic solution on the skin. This is done to open up the skin pores, soften tissues and increase the blood circulation. The acidic solution breaks down the skin oil stuck in the pores, clears the follicles and extracts any skin 

Step 2: Apply an alkaline solution to the skin. This step closes the pores and reduces blood circulation in that area. This also soothes the nerves. 

Step 3: Use a galvanic positive probe to improve the penetration of skin care products. This step is also called as ‘iontophoresis’.
