Question

in the question given below which number can be placed at the sign of interrogation?

Answer 1

the difference between 18 and 10 is 8

in the same way the difference between 17 and 14 is 3

the product of 8 and 3 is 24

Answer 2

Answer: D) 24 is the correct option

Step-by-step explanation:

1) difference of upper digits  5 - 3 = 2 and   difference of lower digits 12 - 9 = 3

Now multiply the difference 2 x 3 = 6

2) difference of upper digits   8 - 4 = 4 and difference of lower digits  2 - 1 = 1

Now again multiply the difference 4 x  1 = 4

Hence in the same manner we have 18 - 10=8  and 17- 14 = 3

Therefore 8 x 3 = 24

Hence, 24 is the required answer
