Question

on selling a transistor set at 15% gain and a radio at 20%loss a shopkeeper gains rs 20. if he sells each of both item at 10% gain, he gains rs 95 . find the price of transistor.​

Answer 1

C.P. of 1sttransistor=Rs.(120100×840)=Rs.700.

C.P. of 2ndtransistor=Rs.(96100×960)=Rs.1000

So, total C.P.=Rs.(700+1000)=Rs.1700.

Total S.P.=Rs.(840+960)=Rs.1800.

∴Gain% =(1700100×100)% =

$5 = \frac{15}{17}$
