Question

find the value of x if the no 25x731 is divisible by 3​

Answer 1

Answer:

56*655*5+1558=511566

Answer 2

If the sum of the digits of a number is divisible by 3 then the number is divisible by 3.

if 25x731 is to be divisible by 3 then the sum of the digits must be divisible by 3.

》 2 + 5 + x + 7 + 3 + 1 = 18 + x

18 is divisible by 3. so if take the value of x as 0

then, 18 + 0 = 18 is divisible by 3.

therefore, value of x = 0.
