Question

1. If 32a8 is a multiple of 9, find the value
of a which is a digit.
2. If 543x is a multiple of 8, find the possible
values of x which is a digit.​

Answer 1

Answer:

5 is the value of a

so the number is 3258 which is divisible by 9

Answer 2

Answer:

a = 5

x= 2

Step-by-step explanation:

in 1

32a8

3+2+8+a is factor of 9

13+a

18is the nearest factor

thus

13+a=18

a=5

in2

by divisibility test of 8

43x÷8

remainder =0

thus

if we put 2 at place of X

then remainder is 0
