If the year 2024 were to show the same percent revenue growth over the year…

Concept

When a quantity grows by the same percentage in two consecutive periods, its multiplying factor stays constant. If a value rises from A to B, that factor is r = B/A and the percentage growth is (B - A)/A × 100. Applying the same percentage growth once more to B therefore gives B × r = B2/A.

Application

1. Total revenue in 2022 = journals 40 + magazines 42 + books 87 = ₹169 lakh.

2. Total revenue in 2023 = journals 40 + magazines 54 + books 79 = ₹173 lakh.

3. Growth factor from 2022 to 2023: r = 173/169, so the percentage growth is (173 - 169)/169 × 100 = 400/169 ≈ 2.3669%.

4. Applying the same factor to the 2023 total: revenue in 2024 = 173 × (173/169) = 1732/169 = 29929/169.

5. Dividing, 29929/169 ≈ 177.0947, so the revenue in 2024 is approximately ₹177.095 lakh.

Cross-check by computing the rise directly: 2.3669% of 173 ≈ 4.0947, and 173 + 4.0947 ≈ 177.0947 - the same figure. Because the growth rate is small and positive, the 2024 total must sit just above the 2023 total of ₹173 lakh.

A common slip is to repeat the absolute rise of ₹4 lakh instead of the percentage. Equal percentage growth acts on the larger 2023 base, so the rise in 2024 is slightly bigger, about ₹4.09 lakh.
