Question

gabbar singh purchased 60kg cereals(rice and wheat) for rs. 700. the cost per kg of rice is rs. 15 and that of wheat is rs. 10. find the quantity of rice and wheat each.

Answer 1

let the quantity of rice be x
total quantity=60kg
then, 15x + (60-x)10 =700
15x + 600- 10x =700
15x - 10x = 700 - 600
5x = 100
x = 100÷5= 20
so, quantity of rice is 20 kg and quantity of wheat is (60kg - 20 kg =) 40kg
