Question

if 724x175 is divisible by 11,then if find the value of x​

Answer 1

Answer:

Divisibility Criteria for 11 = (Sum of numbers at odd places) - (Sum of numbers at even places) should be 0 or 11 (or multiple of 11)

Sum of numbers at odd places = 17

Sum of numbers at even places = 9+x

Now, 17 - (9+x) = 0

17- 9 - x = 0

8- x = 0

x = 8
