Question

A woman bought two parcels of toffees, the same number in each parcel. She bought the first pack at $25$ paise per each toffee and the second pack at $3$ toffees for $65$ paise. She mixed them together and sold at Rs. $3.50$ a dozen. Her gain percent is:

• A. $15\%$
• B. $25\%$
• C. $16\frac{2}{3}\%$
• D. $12\%$

Answer 1

The correct option is B $25\%$

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

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

$\therefore$ 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 $\%=\frac{0.70}{2.80}\times 100=25\%$
