Question

. if the three

digit number

43x is divisible

by what is the

value of x?​

Answer 1

By 3

The value of x will be

“43x” should be divisible by 3, for that it should be divisible by 3*3 or 3

Divisibility of 3 is sum of digits is divisible by 3

So 4 + 3 + x should be divisible by 3 and 0 <= x <= 9

The only solution for this is 2

So the number is 432 which is also divisible by 3

:)

Answer 2

Complete question:

If the three digit number 43x is divisible by 9, what is theIvalue of x?​

Answer:

Divisibility by 9:

A number is divisible by 9 if the sum of the digits are divisible by 9

Sum of digits= 4+3+x = 7+x

If 2 is added to 7, sum of digits become 9 and it is divisible by 9

So,

7+x=9

x=2
