Question

TOFFEES ARE BOUGHT AT 15 FOR ₹20. HOW MANY TOFFEES WOULD BE SOLD FOR ₹20 SO AS TO GAIN 25%

Open in App
Solution

Solution :-

C.P of 15 toffees = Rs 20

C.P of 1 toffee = 20/ 15 => 4/3

So we get C.P of one toffee = 4/3

Now , we are given gain % = 25 %

We know that Formula of S.P = ( 100 + gain /100 ) * C.P

= 100 + 25 4
-------------------- * -----------
100 3

= 125 4
----------- * --------
100 3


= 500 /300 = 5/3

So S.P of one toffee = Rs 5/3

Therefore , Number of toffee sold = Total price/ S.P of one toffee

= 20 / ( 5/3)

= 20 * 3 / 5

= 60 / 5

= 12 Toffees Answer.
