A bag contains 95 coins of 1 rupee, 50 paise and 25 paise. How many 1 rupee coins are there in the bag if there is a total of Rs.50.5 in the bag and it is given that 25 paise coins are 133.33% more in number than 1 rupee coins?
18
A + B + C = 95
A + 0.5B + 0.25C = 50.5
C = 1.333A
Solving, we get 24 coins of 25 paise.
