Question 47

If ‘#’ means ‘—’, ‘&’ means ‘$$\div$$’, ‘@’ means ‘$$\times$$’ and ‘$$\div$$’ means ‘+’, then 15 @ 2 $$\div$$ 900 & 30 # 10 = ?

Solution

By applying the given conditions,

$$15$$ @ $$2$$ $$\div$$ $$900$$ & $$30$$ # $$10$$ $$=15\times2\ +900 \div 30 -10$$

$$=15\times2\ +30\ -10$$

$$=30+30\ -10$$

$$=50$$

Hence, the correct answer is Option C
