Question

A shopkeeper mixed 34kg of sugar which costs 22 50 per kg with 29
kg of sugar which costs 15 per kg at what rate must sell the
mixture so as to gain 5% on the total investment?

Raj Chauhan · Accepted Answer

CP of 34 Kg sugar = 34 x 22 50 = 765 Rs
CP of 29 kg sugar = 29 x 15 = 435 Rs
​Total CP = 765+435 = 1200 Rs
and total weight of sugar = 34 + 29 = 63 Kg

​Find SP on 5 % gain

SP = (100 + gain %)/100 x CP
​= (100 + 5)/100 x 1200 = 1260 Rs

Hence rate must sell the mixture so as to 5 % gain = SP/Total
weight of sugar =
1260/63 = 20 Rs/per kg​
