Shubhada is having total Rs. 300 in coin of denomination Rs. 1, Rs. 2, Rs. 5. No. of 2 Rs. Coin is three times the no. of 5 Rs. Coins. Total no. of coins is 160. How many coins of Rs. 5 are with Shubhada?
1). 35
2). 25
3). 20
4). 40
Let the no. of Rs. 5 coins be ‘x’
Let the No. of 1 Rs. Coin be ‘y’
No. of 2 Rs. Coin be ‘3x’
According to the question,
x + 3x + y = 160 ---- (1)
And, 5x + y + 6x = 300 ---- (2)
By simultaneously solving equations (1) & (2), we get,
x = 20, y = 80
∴ Number of Rs. 1 = 80 coins, Rs. 5 coins = 20 coins, Rs. 2 coins = 60
