100% + 20% (i.e profit) = 120% (for 6 toffees).

120% = 6.
1% = 6/120.
100% = (6/120)*100.

Value for 100% = 5.

Chain rule:

1Rs------ 6 toffees--------100%.

1Rs-------x toffees---------120%.

More Tofees per Rupee results less profit%. There it is inverse proportion.

1*6*100 = 1*x*120====> x = 5.

In question they have given 20%. Why your assuming 120%?

Riya said:   1 decade ago
@Sunil.

That goes by the formula: SP = (100+gain%)*CP/100.

C.P of one toffees = 1/6 and S.P of one toffees = 120/100.1/6 = 1/5.

He must sold 5 toffees to get 20% profit.

C.P. of 1 toffee = 1/6 Rs.

Profit % = 20 %.

Now, profit % = (profit*100)/C.P.

So, profit = 20*(C.P.)/100.

Profit = 1/30 Rs for 1 toffee.

Now, S.P. = C.P.+profit.

S.P. = 1/6+1/30.
S.P. = 1/5 Rs for 1 toffee.

For S.P. = 1 Rs he has to sell 5 toffees.

Guys I think this may be simple for you.

Given 1 rupee = 6 toffees.

So to avoid complexions in calculations.

Let's multiply with 100 on both side.

100 rupees = 600 toffees.

Given profit = 20%.

Sp = Cp+P.
Sp = 100+20.
Sp = 120.

Now, no of toffees = 600/120 = 5.

Hope that you can understand easily. Thank you guys. All the best.

If a man gains 5% by selling nibs at the rate of 34 a rupee, how many rupee must he sell them. So as to gain 19%.

CP of 6 toffee = 1.

Gain = 20%.

Profit% = p*100/cp.
20 = p*100/1.

p = 20*1/100.
p = 1/5.

i.e; for 5 toffees for re. 1.
