Question

raja bought 6dozen of apple rs360.he found 10 apple rotten.he sold rest at rs60 per dozen.how much he gain
or loss

Answer 1

C.P of 6 dozen apple = ₹360
C.P of 1 dozen apple =₹360/6=₹60
1dozen = 12 apple
6dozen = 72 apple
cost of 12 apple =₹60
cost of 1 apple = ₹60/12=₹5
apple left with him = 72-10=62
S.P of 1 dozen apple = ₹60
S.P of 1 apple = ₹60/12=₹5
S.P of 62 apple =₹5×62= ₹310
therefore, loss = C.P-S.P
= ₹(360-310)=₹50
Loss%=Loss/C.P×100
=50/360×100
=125/9%
