Question : 58 of 100

Marks: +1, -0

By mixing two qualities of pulses in the ratio 2 : 3 and selling the mixture at the rate of Rs. 22 per kg, a shopkeeper makes a profit of 10%. If the cost of the smaller quantity is Rs. 14 per kg, the cost per kg of the larger quantity is :

Rs. 23
Rs. 24
Rs. 25
Rs. 26

Validate

Solution:

Cost price of 5 kg
= Rs.

(14 × 2 + x× 3) = (28 + 3x)

Selling price of 5 kg = Rs. (22 × 5) = Rs. 110

{110 - (2 8 + 3 x ) }/{28 + 3x}×100=10

⇒

{82- 3x}/{28 + 3x}=1/10

⇒

820- 30x = 28 + 3x

⇒

33x = 792 ⇒ x = 24
