Question

The bar graph shows the number of deaths in cities 1, 2, 3 and 4 across several months. The average number of deaths that occurred during April across all the cities (rounded off to the next integer) is: [Refer to the bar graph. April values — City 1: 860, City 2: 765, City 3: 960, City 4: 1148.]

1. A. 953
2. B. 965
3. C. 928
4. D. 934 (Correct answer)

Correct Answer

Option D — 934

Detailed Solution & Explanation

The correct answer is 934.

Key Points

• April deaths: $860+765+960+1148 = 3733$.
• Average $=\dfrac{3733}{4}=933.25\approx 934$ (rounded to the next integer).

Additional Information

• Bar-graph averages test careful reading more than arithmetic: take the values for the one month named, across all four cities, and nothing else.
• Note the rounding instruction. Rounded to the next integer sends 933.25 to 934, whereas ordinary rounding would give 933 — and 933 is offered as a distractor.
• Add the values in pairs to reduce slips: (860 + 1148) + (765 + 960) = 2008 + 1725 = 3733.
