Question

If 36x52y8 is divisible by 9, then x+y is​

Answer 1

Step-by-step explanation:

Divisibility Test Of 9 states that any number whose sum of digits is a multiple of 9 is divisible by 9.

Hence, 3+6+x+5+2+y+8 = 9a

24+x+y= 9a

when we put a=3

x+y=27-24

x+y= 3

when we put a=4,

x+y=36-24

x+y=12

THESE ARE THE ONLY TWO VALUES POSSIBLE

SINCE X+Y CANNOT BE MORE THAN 18
