According to the given table, what percentage of candidates scored less than 20% marks in GK?

Correct option is D

Given:

Total candidates = 10,000

We are to find % of candidates who scored less than 20% marks in GK.

Solution:

Score range = 0 – 200, so 20% of 200 = 40 marks
Candidates scoring less than 40 marks in GK = candidates in the 0 – 40 interval.

Percentage =$$\left( \frac{2219}{10000} \right) \times 100$$​

Percentage = 22.19%

22.19% of candidates scored less than 20% marks in GK.
