What approximate value should come in place of the question mark (?) in the following equation? 39.05 × 14.95 - 27.99 × 10.12 = (36.01 + ?) × 4.98

1. 20
2. 30
3. 40
4. 25

Correct answer: 25

Solution

Using approximation, 39.05 × 14.95 ≈ 39 × 15 = 585 and 27.99 × 10.12 ≈ 28 × 10 = 280. Their difference is about 305. Now 305 ÷ 4.98 ≈ 61, so 36.01 + ? ≈ 61, giving ? ≈ 25. Hence, the answer is 25.
