1.	A sum of 500 is in the form of denominations of 75 and 10. If the total number ofnotes is 90 find the number of notes of each denomination(Hint: let the number of 5 rupee notes be *x, the number of 10 rupee notes=90-
Answer» ANSWER: Step-by-step explanation: Let the NUMBER of RS 5 notes be x Total number of notes = 90 Hence the number of Rs 10 notes be (90 − x) Total SUM of money = Rs 500 ∴ 5X + 10 (90 − x) = 500 5x + 900 − 10x = 500 − 5x = 500 − 900 -5x = −400 ∴ x = 80 Hence there are 80 notes of Rs 5 Number of Rs 10 notes = 90 - 80 = 10 Hence there are 10 notes of Rs 10.

A sum of 500 is in the form of denominations of 75 and 10. If the total number ofnotes is 90 find the number of notes of each denomination(Hint: let the number of 5 rupee notes be *x, the number of 10 rupee notes=90-

Answer»

ANSWER:

Step-by-step explanation:

Let the NUMBER of RS 5 notes be x

Total number of notes = 90

Hence the number of Rs 10 notes be (90 − x)

Total SUM of money = Rs 500

∴ 5X + 10 (90 − x) = 500

5x + 900 − 10x = 500

− 5x = 500 − 900

-5x = −400

∴ x = 80

Hence there are 80 notes of Rs 5

Number of Rs 10 notes = 90 - 80 = 10

Hence there are 10 notes of Rs 10.

Answer»

The smallest number DIVISIBLE by 14,24,35 and 77 is their L.C.M ., which is equal to 9240.

Factorising 9240 into PAIRS of equal FACTORS:

9240 = (2×2)×2×3×5×7×11

The factors 2,3,5,7,11 are not paired .

To make 9240 into a perfect square , we have to multiply it by 2×3×5×7×11., i.e., by 2310.

If a candidate scored 450 marks in thetest how many questions did he answer correctly?
Answer» Answer: x=126 Step-by-step explanation: LET the NUMBER of correctly attempted questions be x so, the number of unattempeted or wrong question = 180-x total MARKS for correct attemptions = 4x and total marks for unattempeted or wrong question = -1 (180-x) = x - 180 as total marks = sum of attempted and unattempeted or wrong question = 180-x 450 = 4x + x - 180 450 = 5x -180 630 = 5x 126 = x so, the number of correctly attempted question was 126.

A candidate gets 4 marks for everycorrect answer, and for every un-attempted or wrongly answered questions one mark isdeducted from the total score of correct answers. If a candidate scored 450 marks in thetest how many questions did he answer correctly?

Answer»

Answer:

x=126

Step-by-step explanation:

LET the NUMBER of correctly attempted questions be x

so, the number of unattempeted or wrong question = 180-x

total MARKS for correct attemptions = 4x

and total marks for unattempeted or wrong question = -1 (180-x)

= x - 180

as total marks = sum of attempted and unattempeted or wrong question = 180-x

450 = 4x + x - 180

450 = 5x -180

630 = 5x

126 = x

so, the number of correctly attempted question was 126.

Answer» Step-by-step explanation: The answer is negative. Odd numbers of negative integers when multiplied yield negative integer only. Consider an integer -x = (-1)x. Let -y be another integer. Then product of -x -y = (-1)^2* xy = xy similarly - x* -y* -Z = (-1)^3* xyz = -xyz -x-y-z-s = (-1)^4 xyzs = xyzs proceeding same way, you will observe that multiple of odd negative numbers are RESULTING in negative digit while multiples of even negative numbers will result in POSITIVE digits. A digit when multiplied by positive numbers, the sign of the resultant digit wont change. Hence the answer should be a positive.

Step-by-step explanation:

The answer is negative. Odd numbers of negative integers when multiplied yield negative integer only. Consider an integer -x = (-1)*x. Let -y be another integer.

Then product of -x * -y = (-1)^2* xy = xy

similarly - x* -y* -Z = (-1)^3* xyz = -xyz

proceeding same way, you will observe that multiple of odd negative numbers are RESULTING in negative digit while multiples of even negative numbers will result in POSITIVE digits. A digit when multiplied by positive numbers, the sign of the resultant digit wont change. Hence the answer should be a positive.

Is it passible to have a triangle with the following sides? (a) 3m, 6cm, 7cm, (b) 6cm, 3cm,2cm.

Answer»

Answer:

(a) Yes

(b) No

Step-by-step explanation:

The possibility of a triangle to be formed depends on the the length of sides.

To form a triangle, the sum of the length of TWO sides must be GREATER than the length of third side.

Now, moving to the question.

(a)3CM, 6cm, 7cm

3+6 > 7
3+7 > 6
6+7 > 3

Clealry, in allt the three cases, it satisfies the required condition.

Therefore, triangle will be formed.

(b) 6cm, 3cm, 2cm

6+3 > 2
6+2 > 3
2+3 < 6

In this , two cases are satisfying the required CONDITON but the third case is not.

Therefore, triangle will not be formed.

Hence, triangle will be formed only in (a).

Sum of 1 + 3 + 5 + 7 + 9 + 11 + 13 + 15 ( Sum of First N Odd Numbers )

First 8 Odd Numbers = 8 ² = 64

Step-by-step explanation:

Sum of N Natural Numbers

N ( N + 1 ) / 2

Sum of N Even Numbers

N ( N + 1 )

Sum of N Odd Numbers

Answer» QUESTION The ages of Rahul and Laxmi are in the ratio 5:7. Four years LATER, the SUM of their ages will be 56 years. What are their present ages? ANSWER Let Rahul's AGE and Laxmi's age be x and y respectively. Given The ages of Rahul and Laxmi are in the ratio 5:7. => Rahul = 5X => Laxmi = 7x Four years later, the sum of their ages will be 56 years. $\implies 5x+4+7x+4=56\\\implies 12x+8=56\\\implies 12x=56-8\\\implies 12x=48\\\implies x = 4$ Rahul's age = 4 * 5 = 20 years Laxmi's age = 7 * 4 = 28 years

Answer»

QUESTION

The ages of Rahul and Laxmi are in the ratio 5:7. Four years LATER, the SUM of their ages will be 56 years. What are their present ages?

ANSWER

Let Rahul's AGE and Laxmi's age be x and y respectively.

Given

The ages of Rahul and Laxmi are in the ratio 5:7.

=> Rahul = 5X

=> Laxmi = 7x

Four years later, the sum of their ages will be 56 years.

$\implies 5x+4+7x+4=56\\\implies 12x+8=56\\\implies 12x=56-8\\\implies 12x=48\\\implies x = 4$

Rahul's age = 4 * 5 = 20 years

Laxmi's age = 7 * 4 = 28 years
