Question

Which of the following is an example of indirect proportion?
A.Number of mangoes in a bag and weight of the bag.
B.Earning and Hours worked.
C.More the speed, the less the time taken.
D.None of these.

Answer 1

In order to check for the example of indirect proportion, we need to know first what is an indirect proportion. An indirect proportion also called an inverse proportion, is a proportion in which one quantity is increasing then the other quantity needs to be decreased, that means the two quantities are behaving opposite in nature.

Complete answer: We are given three options, so let’s check out one by one for the correct option.
Option 1:
Number of mangoes in a bag and weight of the bag.
We can see that the weight of the mangoes are directly depending on the number of mangoes, if there are more mangoes more weight, if less mango less weight. So, this proportion is a direct proportion, not indirect. So, it’s not the correct option.
Option 2:
Earning and Hours worked
Since, money is always paid for the amount of work we do. If we work less hours, then less money. If we work more hours, the more money we make. So, this proportion is also a direct proportion, not indirect. So, it’s not the correct option.
Option 3:
More the speed, the less the time taken.
If the speed is increased, it will take less time to cover a distance, If the speed is decreased, more time will take to cover the distance. So, the quantity is increasing and decreasing, if one is increasing then other is decreasing, and vice versa. It’s an indirect proportion. So, it is the correct option.
Hence, the correct option is Option C.

Note:
Direct Proportion is a proportion in which if one quantity is increased then other is also increasing, if one is decreasing then the other must decrease.
Indirect and direct proportions are the essential part of our daily lives and used everytime, because every quantity we use is attached to one another.
