Answer 2

Answer:

The selling price of remaining rice is Rs.624.

Step-by-step explanation:

Given : Man bought a certain quantity of rice at the rate of rs. 650 per quintal. 20% of the rice was spoiled.

To find : At what rate should he sell the remaining rice to gain 20% on the outlay?

Solution :

We know, 1 quintal = 100 kg

Man bought a certain quantity of rice at the rate of Rs.650 per quintal.

i.e. 100 kg of rice = Rs.650

1 kg of rice = $\frac{650}{100}=Rs.6.5$

20% of the rice was spoiled.

i.e. 20 kg of rice is spoiled and remaining were 80 kg.

The cost price of 80 kg of rice is $6.5\times 80=520$

CP=Rs.520

Gain % = 20%

The selling price of the rice is

$SP=\frac{100+P\%}{100}\times CP$

$SP=\frac{100+20}{100}\times 520$

$SP=\frac{120}{100}\times 520$

$SP=624$

Therefore, The selling price of remaining rice is Rs.624.
