Read Solution (Total 6)
-
- loss=c.p-s.p/c.p
=>1-(450/c.p)=0.2
=>c.p=562.5
gain=s.p-c.p/c.p
=>0.2=(s.p/562.5)-1
=>s.p=Rs.675. - 11 years agoHelpfull: Yes(6) No(1)

- from the questions 450s 80%
for getting 20% profit herecover 40% because already given thathe loss 20%
so 4080% is 450 40% us 225
then 450+225=675

- s.p of lamp=450
loss=20%
s.p=80/100*c.p
450=80/100*c.p
c.p=450*100/80
c.p=562.5
so we got the cost price
Now,as to get 20% profit what should be the sp?
so sp =120% of cp
sp=120/100*562.5
s.p=675
answer is 675 - 10 years agoHelpfull: Yes(0) No(0)
- c.p=100/100-20*450
c.p=562.5 of 20% is 112.5
s.p=675 - 10 years agoHelpfull: Yes(0) No(0)
- sp=450 ,loss=80
cp=4500/8
sp=4500*120/8
=> 675 - 8 years agoHelpfull: Yes(0) No(0)
