Question : 87 of 100

Marks: +1, -0

(7.14² + 162.012 ÷ 3.09² − 7.12 × 9.16) = ?

Solution:

Concept:

Use approximate values for each term to simplify the expression quickly.

Explanation:

Replace each number with its nearest integer approximation.

7.14 \approx 7

162.012 \approx 162

3.09 \approx 3

7.12 \approx 7

9.16 \approx 9

So, the expression becomes:

(7^2 + 162 \div 3^2 - 7 \times 9)

= 49 + 162 \div 9 - 63

= 49 + 18 - 63

= 67 - 63 = 4

Answer:

? = 4

Correct option: E. 4
