1 Answer

Answer :

Answer – C (16%)

Explanation – C.P of 20 dozen = Rs.(48 x 20) = Rs.960

C.P of 8 dozen = Rs. (48 x8) = Rs. 384.

C.P of 12 dozen =Rs. (960 – 384) = Rs. 576

Total S.P = Rs. (110/100 x 384 +120/100 x 576) = Rs.1113.60

∴ Profit % = (153.60/960 x 100)% =16%

Description : A salesperson has goods of worth Rs.12000. He sold half of the goods at a gain of 24%. At what profit per cent should he sell the remaining half of the stock so that he gets36% profit on the whole?

Last Answer : CP of goods = 12000 For 36% gain, total SP =12000 + (36/100*12000) = 16320 SP of goods worth 6000 at 24% profit = 6000 + (24/100*6000) = 7440 Therefore, SP of remaining goods = (16320-7440) = 8880 Let ... % for remaining goods be x. Then, =>6000*(100+x)/100=8880 =>100+x=8880/60 x=148-100=48
