How many kilograms of sugar costing Rs. 8 per kg must be mixed with 252 kg of sugar costing Rs. 4.5 per kg so that a profit of 10% maybe made by selling the mixture at Rs. 6.6 per kg?

A.	188kg	B.	189kg
C.	198kg	D.	187 kg

Answer and Explanation

Answer:189kg

Explanation:
S.P = Rs. 6.6/kg.
SP = 110 CP / 100 => CP = (6.6 * 100)/110 = Rs. 6 = Mean Price
Rs. 4.50 / kg      Rs. 8 / kg

                                  [6]

(8-6)                                                (6 – 4.5)
Rs. 2 / kg    Rs. 1.50 / kg

Quantity of dearer / Quantity of cheaper = 1.5/2
Quantity of dearer = 252 x 1.5/2 = 126 x 1.5 = 189 kg.
