Question

Nikhil sold a machine to Sonia at a profit of 33%. Sonia sold this machine to Aruna at a loss of 20%. If Nikhil paid ₹5,200 for this machine, then find the cost price of machine for Aruna.

A.

₹5,532.8

B.

​₹5,632.8

C.

₹5,832.8

D.

₹5,732.8

Correct option is A

Given:

Nikhil's cost price = ₹5200

Nikhil sold it to Sonia at 33% profit

Sonia sold it to Aruna at 20% loss

Formula Used:

Selling Price = Cost Price×(1+Profit %100)\text{Cost Price} \times \left(1 + \frac{\text{Profit \%}}{100} \right)​​

Selling Price (after loss) = Cost Price×(1Loss %100)\text{Cost Price} \times \left(1 - \frac{\text{Loss \%}}{100} \right)​​

Solution:

Selling price from Nikhil to Sonia:

SP = 5200×(1+33100)5200 \times \left(1 + \frac{33}{100}\right)​​

=5200×133100=6916= 5200 \times \frac{133}{100} = ₹6916​​

Sonia sells to Aruna at 20% loss:

Aruna’s Cost Price = 6916×(120100) 6916 \times \left(1 - \frac{20}{100}\right)​​

=6916×0.80=5532.80= 6916 \times 0.80 = ₹5532.80​​
