Question 85

A boy bought 50 chocolates for Rs 1000. If the average price of 30 chocolates is Rs 25, then what is the average price (in Rs) of the remaining
chocolates?

Solution

Total price of 50 chocolates = Rs. 1000

Total price of 30 chocolates = $$30\times25=Rs.$$ $$750$$

=> Total price of remaining $$(50-30=20)$$ chocolates = $$1000-750=Rs.$$ $$250$$

$$\therefore$$ Average price of 20 chocolates = $$\frac{250}{20}=Rs.$$ $$12.5$$

=> Ans - (B)
