RS. 1 -------> 6 TOFFEES.
RS. 10 -------> 60.
20% 0F 10 -------> 20% OF 60.
2 -------> 12.
12 * 5 = 60 i.e for a rupee he sell 5 Toffees to gain 20%.
Similarly A vendor bought toffees at 3 for a rupee. How many for a rupee must he sell to gain 50%?
RS. 1 -------> 3 TOFFEES.
RS. 10 -------> 30.
50% 0F 10 -------> 50% OF 30.
5 -------> 15.
15 * 2 = 30 i.e for a rupee he sell 2 Toffees to gain 50%.
RS. 10 -------> 60.
20% 0F 10 -------> 20% OF 60.
2 -------> 12.
12 * 5 = 60 i.e for a rupee he sell 5 Toffees to gain 20%.

Friends I solved in this manner:
Vendor bought at 6 for a rupee i.e.,6 c.p = 1Rs.
=>1 c.p = 1/6 Rs.
Given as, he must sell to gain 20% i.e., s.p = 120% of c.p.
=>(120/100)*(1/6).
=>1/5.
i.e., for 1 Rs, he bought 5 toffees.

Here is a simple explanation.
Given:
For Rs.1 = 6 toffees.
After profit of 20%.
For Rs 1.2 = 6 toffees
Let for rs.1 = x toffees
Cross multiply,
1.2x = 6.
Which gives x=5 :).

In Question they didn't mention profit is 20%. Then how everyone telling profit is 20%. Please answer my question. And explain the solution in another method if possible?

Let x be taken as 1 rupee :
C.P of 6 toffees = x.
S.P of 6 toffees = 120% of x.
S.P of 6 = 6/5x.
Now 6 * 5/6 = x.
5 = x.
C.P of 6 toffees = x.
S.P of 6 toffees = 120% of x.
S.P of 6 = 6/5x.
Now 6 * 5/6 = x.
5 = x.

Easy way:
Formula:- p% = p*100/c.p.
20 = p*100/1.
p = 20/100 = 1/5.
i.e for rs.1 5 toffees.
Formula:- p% = p*100/c.p.
20 = p*100/1.
p = 20/100 = 1/5.
i.e for rs.1 5 toffees.

It is simple the 20 % profit on 6 toffees 6*20/100 = 6/5 very simple.

Take 1 Rupee=100% so Rq gain = 20 therefore gain =100/20= 5 so. Do like this many problems and ex: if 15 Rs then multiply into 100 1500/20.

I have doubt.
I take each toffee one rupee,
Profit=20%.
Then,
SP-CP/CP *100=20%,
SP=7.2 Rs,
How to relate with this question?
