Let the profit be p .
The CP be denoted by c

From the first case using Profit % formula.

r=(p*100)/c ---1

After S.P is increased by s$

t=((p+s)*100)/c----2

Therefore from 1 and 2

r/t=p/(p+s)

pr+sr=pt

p(t-r)=sr

Put value of r from e.q-1---

p(t-r)=s(p*100)/c

Both P got cancelled

(t-r)=100s/c

c=100s/(t-r)

IMO B.

An item, when sold at a certain price, yields r% profit. Had it been sold for $s more, the profit percentage would have been r%. What is its cost price?

A) \(\frac{100r}{(t-s)}\)

B) \(\frac{100s}{(t-r)}\)

C) \(\frac{s}{100(t-r)}\)

D) \(\frac{st}{100(t-r)}\)

E) \(\frac{(t-r)}{100s}\)


I am confused. I think the question is poorly formulated.

The question stem has no mention of the variable t. I think it should be
