Question

6. Hari bought 20 kg of rice at 36 per kg and 25 kg of rice at * 32 per kg. He mixed the two
varieties and sold the mixture at * 38 per kg. Find his gain per cent in the whole
transaction.​

Answer 1

Step-by-step explanation:

Total weight of rice = 20+25=45

So, total cost of both varieties = (20×36)+(25×32)=720+800=1520

∴ The CP=₹1520

SP=weight×Rate=45×38=1710

Since, SP is more than CP so it’s a gain.

Gain=SP—CP=1710—1520=₹190

Gain%=(Gain×100)/CP

=(190×100)/1520

=12.5%
