(A) 150
(B) 250
(C) 300
(D) 350
(E) 400


Let, Total Toys = 1000

White = (1/4)*1000 = 250
Blue = (3/4)*1000 = 750

Boy Toys = (1/2)*1000 = 500
Girl Toys = (1/2)*1000 = 500

White Toys for Boys = 100
Blue toys for boys = Total Boy toys - Total white toys for boys = 500-100 = 400


Blue toys for girls = Total Blue toys - Blue toys for boys = 750 - 400 = 350

Answer: Option D
