Question

Shastika bought two watches for Rs 3000. She sold one at a loss of 15% and other at a gain of 19% then she found that each watch was sold for the same price. Find the cost price of each watch.​

Answer 1

Answer:

Step-by-step explanation:

Given, Total CP=3000

loss on first watch=15%

gain on second watch=19%

therefore, let SP be $x$

Now, CP of the first watch= $[100/100-loss]*SP$

=[100/100-15]*$x$

=[100/85]$x$

=20/19$x$

Again, CP of the second watch= $[100/100+profit]*SP$

=[100/100+19]*$x$

=[100/19]$x$

comparing:

[20/19]$x$+[100/119]$x$=3000
