Answer 1

per kg cashew = 10% profit

per kg peanut = 10 / 4 = 2.5 % profit

so he sold 166 rs at 20% profit

so no. will be

Let Cp be x

so

\begin{gathered} \frac{120}{100} x = 166 \\ \frac{6}{5} x = 166 \\ x = 16 6 \times \frac{5}{6} \\ x = 27.66 \times 5 = 138.3\end{gathered}

100

120

x=166

5

6

x=166

x=166×

6

5

x=27.66×5=138.3

so cp = 138 rs

so to make profit of 10 %

\begin{gathered} \frac{110}{100} x = 138.3 \\ x = 138 \times \frac{10}{11} \\ x = 12.57 \times 10 \\ x = 125.7\end{gathered}

100

110

x=138.3

x=138×

11

10

x=12.57×10

x=125.7

so 15 - 4 = 11

therefore, 125.7 / 11 × 6 = correct answer

so 125.7 / 11 = 11.42

so, 11.42 × 6 = 68.52 rs

Answer = 68.52 rs
