Question

a man sold two washing machine for 9980 sold one at a gain of 10% and other at a loss of 10% find his gain or loss percent in the world transaction​

Answer 1

Sol - Given :-

For first washing machine

SP = Rs. 9980

P%= 10%

CP= ?

CP= 100/100+P%×SP

=100/100+10×9980

=100/11×998 (BY CUTTING THE ZEROS)

=Rs9072.72

For second washing machine

SP= Rs 9980

L%= 10%

CP= ?

CP= 100/100-L%×SP

=100/100-10×9980

= 100/9×998 (BY CUTTING THE ZEROS).

=Rs11088.88

Now,

Total CP = 9072.72+11088.88

= Rs20161.60

Total SP =9980+9980

=Rs19960

Here, CP > SP

THEREFORE IT IS LOSS

L= CP-SP

=20161.60 - 19960

= Rs 201

L%=L/CP×100

=201/20161.60×100

= 0.0099%.
