Question 34

If $$+$$ means $$\times$$, $$-$$ means $$+$$, $$\times$$ means $$\div$$ and $$\div$$ means $$-$$, then $$9 \times 4 + 2 - 5 \times 10 \div 3 = ?$$

Solution

Expression : 9 x 4 + 2 - 5 x 10 ÷ 3 = ?

$$\equiv9\div4\times2+5\div10-3$$

= $$(18\div4)+(5\div10)-3$$

= $$\frac{9}{2}+\frac{1}{2}-3$$

= $$\frac{10}{2}-3$$

= $$5-3=2$$

=> Ans - (A)
