5.	Maahi takes 9/2 minutes to cross the bridge by car. and Tarun take 10/3 minutes to do the same. who takes more time and by how much? tell me fast plzz
Answer» Answer: Maahi ; 7 / 6 minute. Step-by-step explanation: Time TAKEN by : Maahi is 9 / 2 min ⇒ 4.5 min Tarun is 10 / 3 min ⇒ 3.34 min Obviously, 4.5 is more than 3.34 which means time taken by Maahi is more than the time taken by Tarun. So, for the difference in the time gap : Time by Tarun - time by Maahi - ⇒ ( 9 / 2 ) min - ( 10 / 3 ) min ⇒ ( 27 - 20 ) / 6 min ⇒ 7 / 6 min Hence Maahi TAKES more time ( by 7 / 6 min )

5.

Maahi takes 9/2 minutes to cross the bridge by car. and Tarun take 10/3 minutes to do the same. who takes more time and by how much? tell me fast plzz

Answer»

Answer:

Maahi ; 7 / 6 minute.

Step-by-step explanation:

Time TAKEN by :

Maahi is 9 / 2 min

⇒ 4.5 min

Tarun is 10 / 3 min

⇒ 3.34 min

Obviously, 4.5 is more than 3.34 which means time taken by Maahi is more than the time taken by Tarun.

So, for the difference in the time gap :

Time by Tarun - time by Maahi -

⇒ ( 9 / 2 ) min - ( 10 / 3 ) min

⇒ ( 27 - 20 ) / 6 min

⇒ 7 / 6 min

Hence Maahi TAKES more time ( by 7 / 6 min )

Answer» 210 is the number. Given data: 46 38 42 26 29 44 12 28 12 11 14 12 212 342 ? 60 Options: 210 , 200 , 202 , 205 To find: The number that should fill the given position to find. Solution: Let the number to find be 'x' The logic behind this question is- Taking the ABSOLUTE difference between first two columns upto three rows and then, (1st row diff x 2nd row diff) + (3rd row diff x ( 3rd row diff+ 9)) and that will be the difference between last row two numbers. For first two columns: Row 1: \| 46 - 38 \| = \| 8 \| = 8 Row 2: \| 29 - 44 \| = \| - 15 \| = 15 Row 3: \|12 - 11 \| = \| 1 \| = 1 Applying logical formula: (8 x 15) + ( 1 x ( 1 + 9)) = 120 + 10 = 130 And 130 is the difference between 212 and 342. Similarly, for the next two columns: Row 1: \| 42 - 26 \| = \| 16 \| = 16 Row 2: \| 36 - 28 \| = \| 8 \| = 8 Row 3: \|14 - 12 \| = \| 2 \| = 2 Applying logical formula: (16 x 8) + ( 2 x ( 2 + 9)) = 128 + 22 = 150 As the difference is 150, and the last number in the last column is 60, the last number in the third row will be x - 60 = 150 [Per options, the answer should be >200, so we eliminate -(x-60) possibility] x = 150 + 60 x = 210 Therefore, 210 is the number!

Answer»

210 is the number.

Given data:

46 38 42 26

29 44 12 28

12 11 14 12

212 342 ? 60

Options: 210 , 200 , 202 , 205

To find:

The number that should fill the given position to find.

Solution:

Let the number to find be 'x'

The logic behind this question is- Taking the ABSOLUTE difference between first two columns upto three rows and then,

(1st row diff x 2nd row diff) + (3rd row diff x ( 3rd row diff+ 9))

and that will be the difference between last row two numbers.

For first two columns:

Row 1: | 46 - 38 | = | 8 | = 8

Row 2: | 29 - 44 | = | - 15 | = 15

Row 3: |12 - 11 | = | 1 | = 1

Applying logical formula: (8 x 15) + ( 1 x ( 1 + 9))

= 120 + 10

= 130

And 130 is the difference between 212 and 342.

Similarly, for the next two columns:

Row 1: | 42 - 26 | = | 16 | = 16

Row 2: | 36 - 28 | = | 8 | = 8

Row 3: |14 - 12 | = | 2 | = 2

Applying logical formula: (16 x 8) + ( 2 x ( 2 + 9))

= 128 + 22

= 150

As the difference is 150, and the last number in the last column is 60, the last number in the third row will be

x - 60 = 150

[Per options, the answer should be >200, so we eliminate -(x-60) possibility]

x = 150 + 60

x = 210

Therefore, 210 is the number!
