Let atomic weight of x = Mx
atomic weight of y = M
we know, 
mole = weight /atomic weight 
a/c to question, 
mole of xy2 = 0.1 
so, 
0.1 = 10g/( Mx +2My
Mx + 2My = 100g -------(1)
for x3y2 ; mole of x3y2 = 0.05 
0.05 = 9/( 3Mx + 2My
3Mx + 2My = 9/0.05 = 9 × 20 = 180 g ---(2) 
solve eqns (1) and (2)
2Mx = 80 
Mx = 40g/mol 
and My = 30g/mole
