A man buys some quantity of rice for Rs 5100. He sells one third of it...
5100×1/3 = 1700
Profit @10% on 1700= 170
Now, we want overall 20% profit, hence 20% of rs 5100 = 1020
we already gained 170 hence we will deduct it from rs1020 which will give us balance amt of rs 850.
We have to earn a profit of rs 850 on (5100-1700) rs 3400, hence rs 850/rs 3400 = 25%
A man buys some quantity of rice for Rs 5100. He sells one third of it...
Given:
- The man buys some quantity of rice for Rs 5100.
- He sells one-third of it at a profit of 10%.
- He wants to make an overall profit of 20% on the whole transaction.
To find:
At what percent gain should he sell the remaining two-thirds so as to make an overall profit of 20% on the whole transaction?
Solution:
Let's start by finding the selling price of the one-third quantity that he sells at a 10% profit.
Selling price of one-third quantity:
Profit percentage = 10%
Cost price = Rs 5100
Let the selling price be x.
Profit = Selling price - Cost price
10% of Cost price = x - Rs 5100
(10/100) * Rs 5100 = x - Rs 5100
(10/100) * Rs 5100 + Rs 5100 = x
Rs 510 + Rs 5100 = x
Rs 5610 = x
So, he sells one-third of the rice at Rs 5610.
Now, let's find how much profit he needs to make from the remaining two-thirds quantity in order to achieve an overall profit of 20%.
Overall profit percentage = 20%
Profit from one-third quantity = 10%
Let the profit percentage from the remaining two-thirds quantity be y.
Total cost price = Cost price of one-third quantity + Cost price of remaining two-thirds quantity
Rs 5100 = Rs 5100 + Cost price of remaining two-thirds quantity
Cost price of remaining two-thirds quantity = Rs 0
Total selling price = Selling price of one-third quantity + Selling price of remaining two-thirds quantity
Total selling price = Rs 5610 + Selling price of remaining two-thirds quantity
Profit = Total selling price - Total cost price
Profit = Total selling price - Rs 5100
Profit percentage = (Profit / Total cost price) * 100
20% = ((Total selling price - Rs 5100) / Rs 5100) * 100
Substituting the value of Total selling price:
20% = ((Rs 5610 + Selling price of remaining two-thirds quantity - Rs 5100) / Rs 5100) * 100
Simplifying the equation:
20% = (Selling price of remaining two-thirds quantity / Rs 5100) * 100
Selling price of remaining two-thirds quantity = (20/100) * Rs 5100
Selling price of remaining two-thirds quantity = Rs 1020
Profit from remaining two-thirds quantity:
Profit = Selling price of remaining two-thirds quantity - Cost price of remaining two-thirds quantity
Profit = Rs 1020 - Rs 0
Profit = Rs 1020
Profit percentage from remaining two-thirds quantity:
Profit percentage = (Profit / Cost price of remaining two-thirds quantity) * 100
Profit percentage = (Rs 1020 / Rs 0) * 100
Profit percentage = Infinity
Since the profit percentage is infinite, he cannot sell the remaining two-thirds quantity at any percentage gain to make an overall profit of 20%. Therefore, the correct answer is
