Question

two articles are bought for Rs 1600.one of them is sold at a profit of 20% and the other at a loss of 20%. if the selling prices of both are same, find the cost price of each?​

Answer 1

CP OF FIRST 1920

CP OF SECOND 1280

Answer 2

total cost of article-

$1600 \times 2 = 3200$

cost of 1st article=

$20 \div 100 \times 1600 \\ = 320$

$1600 + 320 = 1920$

cost of 2nd article=

$100 - 20 = 80 \\ 80 \div 100 \times 1600 \\ = 1280$

$1600 - 1280 = 480$
