Question

A trader mixes 2 kg

of butter which costs $8 per kg
with 3 kg of butter which costs $6 per kg. He sells the mixture at $2.55 per 250g. Express his profit as a percentage of his selling price.

Answer 1

33.3333%

Explanation:

Total number of kg- 2+3=5

Total money- (2×8)=16

(3×6)=18

16+18=34

$34=5000g

=250g

(250×$34)÷5000=$1.7

profit-2.55-1.7=0.85

(0.85/2.55)×100=33.333%
