Question 32

By interchanging the given two signs ÷ and -, which of the following equations will be correct?
I. $$143 + 6 \times 18 \div 45 - 3 = 236$$
II. $$133 - 7 + 16 \times 11 \div 37 = 158$$

Solution

$$143+6\times\ 18-\frac{45}{3}=236$$

$$143+6\times\ \frac{18}{45}\ -\ 3=236$$

$$143+108-15=236$$

$$251-15=236$$

$$236=236$$

$$133-7+16\times\ \frac{11}{37}=158$$

$$\frac{133}{7}+16\times\ 11-37=158$$

$$19+16\times\ 11-37=158$$

$$19+176-37=158$$

$$19+139=158$$

$$158=158$$

Hence option A is the correct answer
