If cp is 200, 25% gain is added in sp what is the new sp and Gain ?

A person sold 12 chocolates for a rupee and made a loss of 25%. Find how many chocolates should he sell for a rupee to make 50% profit?

Suppose he sell x chocolates at the cost of 6 chocolates and gain profit or 20%.

By formula,
(6-x)/x*100 = 20.
x = 5.

6 chocolate for = 1 rupee.
1 chocolate for = 1/6 rupee.

//After 20 % increment in chocolate price.

1 chocolate for =1/6+(1/6*20/100)= 1/6+1/30 = 1/5.

So,
1/5 rupee for = 1 chocolate.
1 rupee for = 1/(1/5) = 5.

How many % to 10% loss on the sale price will be the purchase price?

120 is = 6.
1 is = 6/120.

100 is = 6/120*100.
= 5 answer.

CP of 6 Toffees = Re.1 = 100ps.

Required gain% = 20%.
(i.e. for 100Ps the vendor should gain 20ps).

Therefore Profit(P) = 20ps.

We know SP=CP+P.

SP = 100+20 =120.

It means the vendor sold 6 toffees for 120ps.

Now from question:

For 120ps he sold 6 Toffees, then.
For 100ps how many he has to sell.

i.e. 120 ---- 6
100 ---- ?

By Cross multiplying we get,

120*? = 100*6

? = 600/120

? = 5

So to gain 20% as profit, the vendor has to by 6 Toffees per 1Re and has to sell 5 Toffees per 1Re.

Hello friends.

We can do use this method or not?
120/100*x = 6

=> x = 6*100/120
=> x = 5

1 Rs is 100% then 20% is 1/5 so 5 is answer.

By selling toffees at 20 for a rupee a man loss 4%.

To gain 20% for Re 1 he must sell?
