Question 39

By interchanging which two numbers the equation will be correct?
$$3 + 6 \div 2 \times 4 - 7 = 5$$

Solution

Implementing the options one by one, Option D gives the correct answer.

Interchange the position of 6 and 3 in 3 + 6 ÷ 2 × 4 - 7 = 5,

$$6 + {\frac{3}{2}}\times{4} - 7 = 5$$

$$6 + 6 - 7 = 5$$

$$12 - 7 = 5$$

$$5 = 5$$

therefore option D is the answer.
