Question

10. A person buys some apples and mangoes from the
market at a rate such that a mango is twice as costly as
an apple and he sells them such that a mango is thrice
the price of an apple. By selling an apple at twice of its
cost price, he makes 150% profit on the whole. Find
the ratio of mangoes to apples.

Answer 2

Given,

The cost price of mangoes = 2(the cost price of apples)

The selling price of mangoes = 3(the selling price of apples)

SP of apples = 2(Cp of the apples)

Profit = 150%

To Find,

The ratio of mangoes to apples =?

Solution,

Let the number of mangoes be m and the number of apples be a.

Let the cost price of 1 apple be Rs. 1

Also, the selling price of 1 apple = 2 * 1 = Rs. 2

Then profit on 1 apple = 2 - 1 = Rs. 1

The cost price of mango = 2*1 = Rs. 2

The selling price of 1 mango = 3 * 2 = Rs. 6

The profit on 1 mango = 6 - 2 = Rs. 4

The total profit = Profit on mangoes and apple / Total cost

150% = (4m + a)/(2m +a)

150/100 = (4m + a)/(2m +a)

3 / 2 =  (4m + a)/(2m +a)

By cross multiplying, we get

3*(2m + a) = 2*(4m + a)

6m + 3a = 8m + 2a

3a - 2a = 8m - 6m

a = 2m

m / a = 1 / 2

m:a = 1:2

Hence, the ratio of mangoes to apples is 1:2 .Option(c) is the correct answer.
