Question
The number of toy airplanes sold by shop B is 25% more
than the number of toy helicopters sold by the same shop. If the ratio of number of toy gliders sold to number of toy helicopters sold is 5:2, and the total number of toys (airplanes + gliders + helicopters) sold by the shop is 9500, then find the number of toy gliders sold by the shop.Solution
Let the number of toy helicopters sold by the shop be 100x Number of toy airplanes sold = 100x × 1.25 = 125x Number of toy gliders sold = 100x × (5/2) = 250x ATP, 100x + 125x + 250x = 9500 475x = 9500 x = 20 So, number of toy gliders sold = 250 × 20 = 5000
