1. A shopkeeper has sufficient money to buy 50 books. On reduction in the price of each book by Tk. 4, he could buy 10 books more. How much money does he has?
- A. Tk. 1000
- B. Tk. 1000
- C. Tk. 1000
- D. Tk. 1000
Answer: Option B
Explanation:
Let, per price = x
50 × x = (x-4) × 60
বা, 50x = 60x - 240
বা, -10x = -240
সুতরাং , x = 24
Amount of money he has
= (50 × 24) = 1200 TK .
