Question

6. Hari bought 20 kg of rice at 36 per kg and 25 kg of rice at 32 per kg. He mized the to
varieties and sold the mixture at 3 38 per kg. Find his gain per cent in the whole
transaction.​

Answer 1

Step-by-step explanation:

We know that,

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%

∴ The Gain percent is 12.5%
