Question

Ajay bought 15 kg of dal at the rate of Rs. 14.50 per kg and 10 kg at the rate of Rs. 13 per kg. He mixed the two and sold the mixture at the rate of Rs. 15 per kg. What was his total gain in this transaction ?

• A. Rs. 1.10
• B. Rs. 16.50
• C. Rs. 11
• D. Rs. 27.50

Answer 1

The correct option is D Rs. 27.50

C.P. of 25 kg = Rs. (15$\times$ 14.50+10 $\times$ 13)
=Rs. 347.50
S.P. of 25 kg = Rs(25$\times$ 15) = Rs. 375.
$\therefore$ Gain = Rs. (375-347.50) = Rs. 27.50
