Question 42

What will be the value of the following expression, if ‘+’ and ‘$$\times$$’ are interchanged and ‘−’ and ‘$$\div$$’ are interchanged?
$$9 + 2 \div 5 \times 4 − 2 = ?$$

Solution

$$9\times\ 2\ -\ 5\ +\ 4\ \frac{\ 2}{ }=?$$

$$9\ +\ 2\ \frac{\ 5}{ }\times\ 4\ -\ 2=?$$

$$9\times\ 2\ -\ 5\ +\ 2=?$$

$$18\ -\ 5\ +\ 2=?$$

$$13\ +\ 2\ =?$$
$$15=?$$
So, hence the correct answer is option D after interchanging the signs.
