What approximate value will come in the place of the question mark (?) in the following equation? You are not supposed to calculate the exact value. $(?)^2 \times 1.25 = 125$

1. 10
2. 14
3. 20
4. 15

Correct answer: 10

Solution

From $(?)^2 \times 1.25 = 125$, we get $(?)^2 = 125/1.25 = 100$. Therefore, the approximate value of ? is 10.
