C.P.= S.P * 100/100+20%.
= 600/120.
= 5 Answer.

C.P = 6rs
S.P = ?

S.P for gain = (100 + gain%)/(100 * c.p)
= (100 + 20%)/(100 * 6),
= 120/600,
= 1/5,
= 0.5.

We can take it as 5rs.

By selling the articles at Rs 240 a trader gains 25%. So what would be his profit % if he sells the articles at Rs. 216?

Agree @B.Vinoth.

7.2 toffee he has to sell in order to earn 20% profit.

For re 1 is 20% so for 6 it is 120.

6 tofees - Rs. 1.
C.p of 1 tofee - Rs1/6.
Profit = 20%.
C.p/100 = S.p/120.

1/(6 * 100) = S.p/120.
S.p = 5.

Note: Assuming c.p as 100 and profit is 20 i.e s.p = 120.

Lemons are bought at the rate of 3 for rupees 4. At what rate must they be sold to gain 20%?

100 paise/6 = 16.666
Now 1/5(20%) of 16.66 = 3.333 as he needs 20% profit.

So, add 16.66 + 3.44 = 20.
Now he must sell 100/5 i.e 5 for Rs 1.

CP of 6 toffees = Re 1.
Profit % = 20%.

As we know profit % = (profit/Cp) * 100.
20 = profit/1 * 100.

Profit = Re 1/5.

SP for 6 toffees = Profit + Cp.

= (1/5) + 5.
= 6/5.

So SP of 6 toffees = Re 6/5.

For Re 6/5 = 6 toffees.
Re 1= 6 * 5/6 toffees.
Re 1 = 5 toffees.

Yes, even I am a bit confused how come 6/5 became 5/6 * 6 ?
