Directions:
Directions for the following 4 questions: The table below shows the annual Revenue and Expenditure (both in Rs. crore) of a company for five years. Profit in a year = Revenue - Expenditure. Study the data and answer the questions that follow. Year | Revenue | Expenditure 2019 | 120 | 80 2020 | 150 | 90 2021 | 180 | 120 2022 | 200 | 140 2023 | 250 | 175

What was the total revenue (in Rs. crore) over the five years?

• A. 850
• B. 880
• C. 900
• D. 950

Hint:

Try pairing the revenue figures from the two ends of the table inward before adding, rather than summing all five numbers in one pass.

Answer 1

The Correct Option is C

Step 1: Instead of adding all five revenue figures straight across, group them into convenient pairs first to simplify the arithmetic.
Step 2: The revenue figures for 2019 to 2023 are $120$, $150$, $180$, $200$, $250$ crore.
Step 3: Pair the first and last values: $120+250=370$. Pair the second and fourth values: $150+200=350$.
Step 4: Add these two partial sums along with the middle value: $370+350=720$, then $720+180=900$.
Step 5: Total revenue over the five years $=900$ crore. \[\boxed{900}\]
