Answer

Correct Answer : d ) 7

Explanation :

If the sum of digits of a number is divisible by 9, then the number will also be divisible by 9.

If 627x5 is divisible by 9, the sum of digits will also be divisible by 9

Sum of digits of 627x5 = 6 + 2 + 7 + x + 5

Sum of digits of 627x5 = 20 + x

If x = 0, 20 + x = 20, not divisible by 9.

Now, x will be any value from 0 to 9.

after 20, 27 will be divisible by 9, when 20 + x = 27

20 + x = 27

x = 7

Hence, (d) is the correct answer.
