Question

Gopi sold a watch to Ibrahim at 12% gain and Ibrahim sold it to John at a loss of 5%.If John paid 1330,then find how much did Gopi sold it?

Answer 1

Cp of John=Sp of Ibrahim
1330=1330
L% 2 Ibrahim=5
Cp of Ibrahim=95/100×1330=1263.5
Cp of Ibrahim=Sp of Gopi
1263.5=1263.5
G% 2 Gopi=12

So,Cp of Gopi=112/100×1263.5=1415.2
