Question

a man sells his goods at 10 percentage gain if he sells it at 15 percentage gain he gets rupees 80 more find cost price of his goods​

Answer 1

Answer:

1600 rupees

Step-by-step explanation:

Let the CP be x Rs.

SP at 10% profit = x + 10x = 110x

100 100

SP at 15% profit = x + 15x = 115x

100 100

Difference between SP at 15% and 10% profit = 80 rupees

115x – 110x = 80 rupees

100

115x – 110x = 80 × 100 rupees = 8000 rupees

5x = 8000 rupees

x = 8000 rupees ÷ 5

= 1600 rupees.

Answer 2

Answer:

Let the cost price be p

Selling price at 10% gain =p(1+10/100)=p×1.1

S.P. at 15% gain=p×1.15

It is given

p×1.15-p×1.1=80

p(0.05)=80

p=80/0.05=1600
