Question 8

If ‘$$+$$’ means ‘$$-$$’, ‘$$-$$’ means ‘$$\times$$’, ‘$$\times$$’ means ‘$$\div$$’ and ‘$$\div$$’ means ‘$$+$$’, then what will be the value of the following expression?$$25 - 2 + 32 \times 8 \div 4$$

Solution

As forgiven question  $$25 - 2 + 32 \times 8 \div 4$$

$$\Rightarrow 25 \times 2 -32 \div 8 + 4$$ (we change the sign for the given condition)

$$\Rightarrow 25 \times 2 - 4 + 4$$

$$\Rightarrow 50 - 4 + 4$$

$$\Rightarrow 50$$ Ans
