Answer 1

Answer:

please mark as brainliest

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%

Answer 2

We know that,

∴ 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%

Formula for gain and loss percent -:

Gain % = (Gain / CP) x 100.

Loss % = (Loss / CP) x 100.
