₂ of them at the rate of Rs. 5 each and the rest at the cost price. My profit percent is -

144%
244²/₃%
344⁴/₉%
445%

Answer:- 1

Explanation:-

Solution:

Total C.P. = Rs. (120 × 3) = Rs. 360
Total S.P. = Rs. (40 × 4 + 60 × 5 + 20 × 3) = Rs. 520
Profit = Rs. (520 - 360) = Rs. 160

$\eqalign{ & \therefore {\text{Profit}}\% \cr & = \left( {\frac{{160}}{{360}} \times 100} \right)\% \cr & = \left( {\frac{{400}}{9}} \right)\% \cr & = 44\frac{4}{9}\% \cr}$
