Answers
c= ₹161
d= ₹179
ratio= 5:4
(cp of mixed rice in 5:4)
(161×5 + 179×4)/ 5+4
=1521/9= ₹169
sp-cp = p
sp= ₹202.80
202.80-169= 33.8
(calculate p% based on cp)
(33.8×100)/169
=20%
Given : A shopkeeper mixes two varieties of rice one costs 161 per kg and other costs 179 per kg in the ratio 5 : 4 respectively.
He sells the mixed variety at 202.80 per kg.
To Find : his profit percentage.
Solution:
Variety A = 5x kg
Variety B = 4x kg
Total = 9x kg
Variety A cost = 161 * 5x = 805x Rs
Variety B cost = 179 * 4x = 716x Rs
Total cost = 805x + 716x = 1521x Rs
Selling price = 202.80 * 9x = 1825.2x Rs
Profit = 1825.2x - 1521x = 304.2x Rs
Profit % = ( 304.2x/1521x) * 100 = 20 %
his profit percentage is 20 %
