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

A 20
B 80
C 200
D 2000

Correct Answer: 200

Let the number of 10 paisa coins be P. Now, 170 TK = 17000 paisa Then, 10P + 25P + 50P = 17000 or,  85P = 17000 or,   P = 17000/85 = 200
