Question

Find direct or inverse variation If 25 horses consume 18 quintal in 36 days how long will 28 quintal last for 30 horses

Answer 1

it is a direct variation
we will take quintal and days first
quintal = 18 28
days = 36 x
now we will do cross multiplication
so 18 × x = 36 × 28
now next x= 36×28÷18
= 56 days
