Question

A shopkeeper contains apples, oranges and bananas in the ratio 5:7:8. There is a demand to
increase their quantity by 50% 60% and 70% respectively. What will be ratio of the
increased quantity?​

Answer 1

Step-by-step explanation:

Increased ratio of apples = 5/100×50

= 2.5

Increased ratio of oranges = 7/100×60

= 4.2

Increased ratio of bananas = 8/100×70

= 5.6

Answer 2

Given: A shopkeeper contains apples, oranges and bananas in the ratio 5:7:8. There is a demand to increase their quantity by 50% 60% and 70% respectively.

To find: We have to find the ratio of the increased quantity.

Solution:

A shopkeeper contains apples, oranges and bananas in the ratio 5:7:8.

Let the amounts of apples, oranges and bananas be 5x, 7x and 8x.

There is a demand to increase their quantity by 50% 60% and 70% respectively.

So, the increase in the quantity of Apple is

$5x \times \frac{50}{100} \\ = 2.5x$

So, the increase in the quantity of orange is

$7x \times \frac{60}{100} \\ 4.2x$

So, the increase in the number of bananas is

$8x \times \frac{70}{100} \\ = 5.6x$

Thus, the ratio of the increased quantity is as follows-

2.5:4.2:5.6

or, 25:42:56.

Thus, the ratio of the increased quantity is 25:42:56.
