A person has only Rs. 1 and Rs. 2 coins with her
A person has only Rs. 1 and Rs. 2 coins with her. If the total number of coins that she has is 50 and the amount of money with her is Rs. 75, then the number of Rs. 1 and Rs. 2 coins are, respectively.
- 30 and 20
- 35 and 15
- 25 and 25
- 15 and 35
Answer
Let number of 1 rupee coins = x and 2 rupee coins = y
Total number of coins is 50
x + y = 50 or x = 50 - y
Amount of money is Rs.75
x + 2y = 75
50 - y + 2y = 75
y = 25, x = 25
The correct option is C.
