see as it is divisible by 275 means y will be either 5 or, 0

that is the resultant should be divisible by 11

thus the 33xy2y should be divisible by 11. That is the difference of sum of digits at odd place with the sum of digits at even places should be either 0 or, 11, or, multiple of 11

sum of odd place digits is 5+x and sum of even place digit is 3 +2y

Difference is (5+x)  (3+2y) it should be either 0 / 11/ multiple of 11

when y = 0 therefore we have 2 + x (it should be 0 / 11 / multiple of 11) but in no case it is possible so Y cannot be 0

so when y = 5 then we have 2 + x  2*5 = 2 + x 10 = 8 + x

yes but then it is not divisible by 275

if x = 9 in that case it is not divisible by 275

shegBest ResponseYou've already chosen the best response.3
now we got 8 + x for what value of x u will have either 0 / 11 / multiple of 11
