Question

Dinesh bought 40 kg mangoes at Rs 25 per kg and
'10 kg mangoes at Rs 20 per kg. At what rate per
kg should he sell them to gain 25%​

Answer 1

Step-by-step explanation:

CP of 40kg mangoes= Rs 25 * 40

= Rs 1000

CP of 10kg mangoes= Rs 20 * 10

= Rs 200

Total CP = Rs ( 1000+ 200)

= Rs 1200

profit = 25%

$sp = cp \times \frac{100 + profit\%}{100} \\ \: \: \: \: \: = rs1200 \times \frac{100 + 25}{100} \\ \: \: \: \: \: = rs1200 \times \frac{125}{100} \\ \: \: \: \: \: = rs 12 \times 125 \\ \: \: \: \: \: = rs1500$

rate of SP = sp/ total weight

= Rs 1500/(40+10)kg

= Rs 1500/50

= Rs 30

Answer 2

Answer:

₹30 per kg

Step-by-step explanation:

Step-by-step explanation:

CP of 40kg mangoes= Rs 25 * 40

= Rs 1000

CP of 10kg mangoes= Rs 20 * 10

= Rs 200

Total CP = Rs ( 1000+ 200)

= Rs 1200

profit = 25%

\begin{gathered}sp = cp \times \frac{100 + profit\%}{100} \\ \: \: \: \: \: = rs1200 \times \frac{100 + 25}{100} \\ \: \: \: \: \: = rs1200 \times \frac{125}{100} \\ \: \: \: \: \: = rs 12 \times 125 \\ \: \: \: \: \: = rs1500\end{gathered}

100

125

=rs12×125

=rs1500

rate of SP = sp/ total weight

= Rs 1500/(40+10)kg

= Rs 1500/50

= Rs 30
