Question

nasir sold a painting for rs 2000 and made a profit of 25% what is his cost price ?

Answer 1

s = c * (1+r)

s is the selling price

c is the cost

r is the interest rate

in your problem:

s = 2000

c = what you want to find

r = .25

equation becomes:

2000 = c * (1.25)

divide both sides by 1.25 to get:

2000 / 1.25 = c

solve for c to get:

c = 1600.

he paid 1600.

he made 25% of 1600 which is 400.

selling price was 2000.
