A number is given as 987562153ab where a and b are digits. Which values of a and b, such that

a + b = 11 and a < b,


would result in 987562153ab being divisible by 4?

(A) a = 0 , b = 8
(B) a = 3 , b = 8
(C) a = 7 , b = 8
(D) a = 5 , b = 6
(E) a = 3 , b = 4

987562153ab divisible by 4 last towdigit should be divisible by 4 i.e ab should be divisible by 4
a+b=11 a<b

so a and b can take following values( 2,9)(3,8)(4,7)(5,6)
out of this only 5,6 make sense
so a,b=56
