What approximate value will come in the place of the question mark in the following equation? $(17.97\% \text{ of } 5235.79) \div ? = (124.97\% \text{ of } 5.09)$

1. 21
2. 183
3. 167
4. 139

Correct answer: 21

Solution

Approximate $17.97\%$ as $18\%$ and $124.97\%$ as $125\%$. Then the equation becomes roughly $(0.18 \times 5235.79)/? = 1.25 \times 5.09$, which gives a value close to 21.
