Correct Answer

✅ Option a — 25

All Options:

  • A25
  • B65
  • C90
  • D27

Detailed Solution & Explanation

Let us analyze the given cumulative frequencies of the "below" type:
- Number of workers earning below ₹ 300: N(Below 300)=65\displaystyle N(\text{Below } 300) = 65
- Number of workers earning below ₹ 400: N(Below 400)=90\displaystyle N(\text{Below } 400) = 90

The total number of workers earning below ₹ 400 represents the total count of workers up to the highest wage category given, which is 90\displaystyle 90.
To find the number of workers who got wages more than ₹ 300, we subtract the number of workers earning below ₹ 300 from the total number of workers earning below ₹ 400:
Workers earning more than 300=N(Below 400)−N(Below 300)\text{Workers earning more than } 300 = N(\text{Below } 400) - N(\text{Below } 300) Workers earning more than 300=90−65=25\text{Workers earning more than } 300 = 90 - 65 = 25
Hence, **Option A** is the correct answer.
