In a cash box, there are equal number of 10 paisa, 25 paisa and 50 paisa coins. If it contains Tk. 170, then what is the number of 10 paisa coin?

A 100
B 200
C 220
D 150

Correct Answer: 200

Let's assume that there are 'x' coins of each denomination (10 paisa, 25 paisa, and 50 paisa) in the cash box.The value of x 10 paisa coins = 0.10x TkThe value of x 25 paisa coins = 0.25x Tk The value of x 50 paisa coins = 0.50x TkSo we can write an equation as:0.10x + 0.25x + 0.50x = 170Simplifying this equation, we get:0.85x = 170Dividing both sides by 0.85, we get:x = 200Therefore, there are 200 coins of each denomination in the cash box, and the number of 10 paisa coins is also 200.
