I have a total of Rs 300 in coins of denomination Re 1, Rs 2 and Rs 5. The number of Rs 2 coins is 3 times the number of Rs 5 coins. The total number of coins is 160. How many coins of each denomination are with me?

Let the of Rs 5 coin be x

Then, No of Rs 2 coins = 3x

And no of 1 Rs coin = 160 –(3x+x) = 160 - 4x
