Question 4

# Which two signs need to be interchanged to make the following equation correct? $$48 - 8 \div 4 + 5 \times 6 = 32$$

Solution

Given expression  $$48 - 8 \div 4 + 5 \times 6 = 32$$

check option (A) $$\times and +$$

we put the sign from the given expression

$$48 - 8 \div 4 \times 5 +6 = 32$$

LHS $$48 - 8 \div 4 \times 5 +6$$

$$\Rightarrow 48-2\times 5 +6$$

$$\Rightarrow 48 - 10 +6$$

$$\Rightarrow 44$$ its not staisfied RHS

then we check option (B) $$\div and -$$

we put sign from the given option

$$48 \div 8 -4 + 5 \times 6 = 32$$

LHS $$48 \div 8-4 +5 \times 6$$

$$\Rightarrow 6-4 + 30$$

$$\Rightarrow 32$$ RHS it is verified RHS

therefore option (B)$$\div and -$$ Ans
