Question

Find the value of X for which the no. X806 is divisible by 9.Also, find the no.

Answer 1

Step-by-step explanation:

We know that , a no. is divisible by 9 when the sum of the digits is divisible by 9

Therefore,

x + 8 + 0 + 6 = x + 14 must be divisible by 9

The nearest number to 14 i.e. is divisible by 9 is 18

Therefore , x+ 14 = 18

x = 4

Note: We taking the nearest no. to 14 more than 14 because we are adding x not substracting .
