Question

a shopkeeper sold two washing machine for RS 49500.on one he gains 10% and the on other he loses 10%. find the gain or loss percent in the whole transaction. ​

Answer 1

There was a 1% loss in the transaction.

Two wachine machines are sold at Rs 49500 each.

On one he gains 10%.

So, on that machine, the CP would be lesser.

CP = 49500/(100+10)%

= Rs 49500/110%

= Rs 45000

On the other he suffers a loss of 10%.

So, on that machine the CP would be more.

CP = 49500/(100-10)%

= Rs 49500/90%

= Rs 55000

TOTAL SP = Rs (49500*2) = Rs 99000

TOTAL CP = Rs (45000+55000) = Rs 100000

Since CP>SP, it's loss

Loss value = Rs 100000- Rs 99000 = Rs 1000

Loss % = [Loss/CP * 100]%

= (1000/100000) *100%

= 1%

This is the required answer.
