Question

-) By selling a painting for? 5280, Rahul made 10% profit. For how much should he have sold it
to make 15% profit ​

Answer 1

sp of painting 5280

profit%=10%

sp-cp/cp*100=10

5280-cp/cp*100=10

528000-100cp=10cp

528000=10cp+100cp

528000=110cp

528000/110=cp

4800=cp.

cp of painting=4800

proft%=15%

sp-cp/cp*100=15

sp-4800/4800*100=15

100sp-480000=15*4800

100sp-480000=72000

100sp =72000+480000

100sp=552000

sp=552000/100= rs5520
