Try taking number of girls and boys be 'x' and '2x' Sum of height of girls = 162x and Sum of height of boys = 364x Mean of whole class = (Sum of height of girls + Sum of height of boys)/ (No. of girls + No. of boys) =(162x+364x) / (x+2x)

Since y=3 find x ...keep x on LHS x=3-2y/4 now here quartile deviation is not affected by change of origin so x=2y/4 or 6/4 or 3/2 is 1.5
