Question

if 45 kg of sugar cost 1305 Rs, what is the rate of sugar per kg?​

Answer 1

Selling Price = Cost Price + Profit (SP = CP + P)

Selling Price = Cost Price + Profit (SP = CP + P)Profit on sale of 45 kg sugar = Selling Price of 5 kg sugar : 45P=5(C+P)

Selling Price = Cost Price + Profit (SP = CP + P)Profit on sale of 45 kg sugar = Selling Price of 5 kg sugar : 45P=5(C+P) 45P=5C+5P

Selling Price = Cost Price + Profit (SP = CP + P)Profit on sale of 45 kg sugar = Selling Price of 5 kg sugar : 45P=5(C+P) 45P=5C+5P 45P−5P=5C

Selling Price = Cost Price + Profit (SP = CP + P)Profit on sale of 45 kg sugar = Selling Price of 5 kg sugar : 45P=5(C+P) 45P=5C+5P 45P−5P=5C 40P=5C

Selling Price = Cost Price + Profit (SP = CP + P)Profit on sale of 45 kg sugar = Selling Price of 5 kg sugar : 45P=5(C+P) 45P=5C+5P 45P−5P=5C 40P=5C P/C=(5∗100)/40

Selling Price = Cost Price + Profit (SP = CP + P)Profit on sale of 45 kg sugar = Selling Price of 5 kg sugar : 45P=5(C+P) 45P=5C+5P 45P−5P=5C 40P=5C P/C=(5∗100)/40 P/C=500/40

Selling Price = Cost Price + Profit (SP = CP + P)Profit on sale of 45 kg sugar = Selling Price of 5 kg sugar : 45P=5(C+P) 45P=5C+5P 45P−5P=5C 40P=5C P/C=(5∗100)/40 P/C=500/40 12.5 %

Selling Price = Cost Price + Profit (SP = CP + P)Profit on sale of 45 kg sugar = Selling Price of 5 kg sugar : 45P=5(C+P) 45P=5C+5P 45P−5P=5C 40P=5C P/C=(5∗100)/40 P/C=500/40 12.5 %So, profit margin on Cost Price is 12.5%

Answer 2

Let the cost of 1kg of sugar be Rs.x

Given

The cost of 45kg of suagr=Rs.1305

The cost of 1kgof sugar = Rs x

Therefore

1305/X =45

or,261/X =9

or,29/X =1

or, 29=X

x=29

The cost of 1kg of sugar is Rs29
