Question

if 42 × 5 is a multiple of 9 and X is a digit then find the value of x ​

Answer 1

Answer:

x = 7

Step-by-step explanation:

For divisibility from 9, the sum of all digits should be divisible by 9.

Thus, 4 +2 +x +5 = 11+x should be divisible by 9.

so, 7 is the only Natural digit which will be here, so that 11+7 = 18 (which is divisible by 9).
