What approximate value will come in place of the question mark in the following expression? 39.789 + 15.9 ÷ 4.1 - 100 ÷ 50.2 + 12.1 × 22.78 = ?

1. 308
2. 318
3. 328
4. 402

Correct answer: 318

Solution

Using approximation, 15.9 ÷ 4.1 is about 3.9, 100 ÷ 50.2 is about 2, and 12.1 × 22.78 is about 275.6. Adding these with 39.789 gives a value close to 318, so the nearest option is 318.
