Question

98x2572 is exactly divisible by '9'.find x value?

Answer 1

Answer:

x = 3

Step-by-step explanation:

For 98x2572 to be divisible by 9, 9+8+x+2+5+7+2 should be a multiple of 9

9+8+x+2+5+7+2 = 33+x

Also, x is a single digit, so 1 ≤ x ≤ 9

Multiple of 9 next to 33 are 36 and 45

x = 36-33 = 3 ✓

x = 45-33 = 12 (not possible since x is single digit)

So, x = 3
