Q.4 Cost of 5 kg of wheat is Rs 91.50.
(a) What will be the cost of 8 kg of wheat?
(b) What quantity of wheat can be purchased in Rs 183?

(a) Cost of 5 kg of wheat = Rs 91.50
Cost of 1 kg of wheat = Rs 91.50/5
Cost of 8 kg of wheat = Rs ( 18.3 x 8)
= Rs 146.40
Thus, the required cost = Rs 146.40
(b) Wheat purchased in Rs 91.50 = 5 kg
Wheat purchased in Rs 1 = (5 / 91.50 )kg
So, wheat purchased in Rs 183 = (5 / 91.50) × 183
= 10 kg
