Question

solve the following : - 573 x 2 X C-3) × (-5)​

Answer 1

Step-by-step explanation:

573 xy is divisible by 90 i.e. (9 x 10)

⇒ 573 xy is divisible by both 9 and 10

⇒ y = 0 as a number is divisible by 10 if its digit =0

sum of digits = 5 + 7 + 3 + x + 0 = 15 + x

For divisibility by 9, 15 + x = 18 ⇒ x = 3

∴ x + y = 3 + 0 = 3
