Question

a person purchased two watches for 650. if he sells one watch at 20%gain and other at 25%loss,then the selling price of two watches are equal find the cost price of each watch​

Answer 1

Answer:

this your answer

Let the cost price (C.P) of A be Rs x

and that of B be Rs y 3

Total cost =Rs650  - [Given]

∴x+y=650

For A 

Profit =20%

Profit %=C.PProfit×100

∴20=C.PofAsellingpriceof(S.P)−C.PofA×100

∴51=xS.P−x

∴S.P. of A=56x

For B 

Loss =25%

Loss% C.PLoss×100

25=C.PofBC.PofB−sellingprice(S.P)ofB×100

41=yy−S.P

4y=y−S.P. of B 

∴ SP of B =43y

But, according to the given concoction 

S.P of A=S.P of B 

56x
