Question

Table – Daily Wages of 5 Workers Over 4 Days. What is the average daily earning of Worker C?

1. A. 222.5 (Correct answer)
2. B. 222
3. C. 227.5
4. D. 215

Correct Answer

Option A — 222.5

Detailed Solution & Explanation

The correct answer is 222.5.

Key Points

• Read down the Worker C column across the four days: 220, 230, 215, 225.
• Sum = 220 + 230 + 215 + 225 = 890.
• Average = 890 ÷ 4 = 222.5.

Additional Information

• The first discipline in table-based questions is locating the right row and column; reading Worker B or D here produces one of the other options exactly.
• A shortcut for closely grouped figures is to take a base and average the deviations: with base 220, the deviations are 0, +10, −5, +5, summing to +10, so the average is 220 + 10/4 = 222.5.
• Data interpretation carries a reliable block of marks in SSC CGL because no recall is needed — the entire answer is on the page, and accuracy matters more than speed.
