How many persons earn ₹200 or more but less than ₹300?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is Option 3 i.e 22.
According to the question,
There are 12 people who earn less than ₹200.
There are 26 people who earn less than ₹250. In this case, 12 people were also included who earn less than ₹200.
So one can say that there are 14 people ( 26 - 12 ) who earn more than ₹200 but less than ₹250.
There are 34 people who earn less than ₹300. In this case, those 26 people also included who earn less than ₹250.
So one can say that there are 8 people ( 34 - 26) who earn more than ₹250 and less than ₹300.
The total number of a person who earns more than ₹200 and less than ₹300 = 14 + 8 = 22.
