Question

gopi sold a watch oi ibrahim at 12% and ibrahim sold it to john at a loss of 5% .If John paid Rs1,330, then find how much did gopi sold it?

Answer 1

cp of the watch = Rs 1330

sp of the watch = (cp*100)/(100+g)*100/(100 -l)

= (1330*100)/(100+12)* (100)/(100-5)

= (1330 *100*100)/(112*95)

= Rs 1250
