Question

A WOMAN BOUGHT 2 PACKS OF TOFFEES, WITH THE SAME NUMBER OF TOFFEES IN EACH PACK. SHE BOUGHT THE FIRST PACK AT 25 PAISE PER TOFFEE AND THE SECOND PACK AT 3 TOFFEES FOR 65 PAISE. SHE MIXED THEM AND SOLD THEM AT RS. 3.50 A DOZEN. WHAT IS HER GAIN PERCENT?

Answer 1

Correct option is

B

25%

In the first pack, the amount she pays for 3 toffee =3×25=75 paise.

In the second pack , the amount she pays for 3 toffee =65 paise

∴ for 6 toffee she pays 75+65= Rs. 1.40

And for a dozen she pay =1.40+1.40= Rs. 2.80

S.P. of 1 dozen toffees = Rs. 3.50

C.P. < S.P

Profit =3.50−2.80=0.70=70 paise

Profit %=

2.80

0.70

×100=25%
