Question

two lots of oranges with equal quantity, one costing rs. 20 per dozen and the other costing rs. 30 per dozen, are mixed together and the whole lot is sold at rs. 24 per dozen. then what is the proď¬t or loss?

Answer 1

when two doze are mixed togather
then cost price of both =20+30
=50
one dozen is sold at =rs 24
then two dozen are sold at =2×24
= 48rs
sp=48
cp = 50
loss = cp-sp
= 50-48
= 2rs
loss%= loss×100/cp

= 2×100/50
= 200/50
= 4%
