Question :

A vegetable vendor bought 25 kg of potatoes at 7Rs.Per kg and 15 kg at 8rs per kg.At what rate should he sell them to gain 22% .

Answer :

$\sf\purple{Given}$

• 25 kg potatoes were bought at 7 Rs . per kg .

• 15 kg potatoes were bought at 8 Rs . per kg .

$\sf\purple{To\:Find}$

• What should be the selling price to gain a total gain of 22% = ?

Explanation :

• cost price of 25 kg potatoes bought at 7 Rs per kg = 25×7

$\longrightarrow\sf\pink{175 Rs }$

• cost price of 15 kg potatoes bought at 8 Rs per kg = 15 × 8

$\longrightarrow\sf\pink{120 Rs }$

• Total cost price of 25 kg and 15 kg potatoes = 175 + 120

$\longrightarrow\sf\pink{ 295 Rs }$

Selling Price = 100 + gain % /100 × C . P

$\longrightarrow\sf{100 + 22 /100 × 295 }$

$\longrightarrow\sf{122 /100 × 295 }$

$\longrightarrow\sf{122 /100 × 295 }$

$\longrightarrow\sf{35990/100}$

$\longrightarrow\sf{3599/10}$

$\longrightarrow\sf\pink{359.9}$

• Therefore he should sell them for Rs 359 . 9
