Hi Dookie,

let the first no be x.

x/n = (an integer) + 11 = u + 11 - equation 1

similarly

y/n = (an integer) + 21 = v + 21 - equation 2

(x+y)/n = (an integer) + 4 = w + 4 - equation 3

eq1+eq2 = eq3 - equation 4

simplifies

n(u+v) + 32 = nw + 4 - here u,v,w are integers.

this means that n is a factor of 28.........bcoz n<=32-4 or n<=28

the factors of 28 are 14,7 etc.

since we have seen a remainder of 21 this means that n>21 , therefore n=28.
