Question

Two articles are sold for rs. 396 each. on one, he gains 10% and on other he losses 10%. find his gain or loss

Answer 1

Given:

SP of two articles = Rs. 396

Gain = 10%

Loss = 10%

To Find:

The gain or loss %

Solution:

Let CP be = x

Let SP be = y

Profit % x = SP = CP x ( 100 + x)/100

Profit % y = SP = CP x ( 100 - x) /100

Since two articles are sold, therefore -

Total SP = 396 x 2

Total SP = 792

CP of first article

= 396 x 100/110

= 3960/11

= 360

CP of second article

= 396 x 100/90

= 3960/9

= 440

Thus,

Total CP = 360 + 440

= 800

Loss = 800 - 792

= 8

Loss % -

= 8/800 x 100

= 1%

Answer: The Loss percent is 1%.
