Question

Ayan sold a watch to vineet at a gain of 12% abd vineet sold it to priya at a loss of 5% . If priya paid ₹13350 for it , how much did vineet pay for the watch.

Answer 1

vineet had paid 14017

Answer 2

Let the CP for Vinod be Rs.x.

Profit%. = 12%

SP for Vinod = (1+r/100)*CP

= (1+12/100)*Rs.x

= Rs.28x/25

SP for Vinod = CP for Arun

CP for Arun. = Rs.28x/25

Loss%. = 5%

SP for Arun. = (1-r/100)*CP

= (1-5/100)*Rs.28x/25

= 24/25*Rs.28x/25

= Rs. 6x/7

SP for Arun = CP for Manoj

CP for Manoj= Rs.6x/7

But the given CP for Manoj is Rs.3990.

Rs.6x/7. = Rs.3990

Rs.x. = Rs.3990*7/6

= Rs. 4655 ans.
