What will come in the place of the question mark (?) in the following expression? \(88 \div 44 \times 21 + 117 + 10 = ?^2\)

1. 10
2. 12
3. 17
4. 13

Correct answer: 13

Solution

Using BODMAS, \(88 \div 44 = 2\), and then \(2 \times 21 = 42\). Adding the remaining terms gives \(42 + 117 + 10 = 169\), which is \(13^2\). Hence, the missing number is 13.
