Answer:
No. of
I) 25p coins is 100
II) 50p coins is 50
Step-by-step explanation:
Let the number of 25 paise coins be x and number of 50 paise coins be y. Then,
x + y = 150. ..1
25x + 50y = 5000 (paise)
25x + (25 × 2y) = 5000
25x + 25(2y) = 5000
25(x+2y) = 5000
x + 2y=200. ..2
On subtracting equation 1 from equation 2, we get
x + 2y = 200
- x + y = 150
y = 50
On substituting y = 50 , we get
x + 50 = 150
x = 100
So , no. of 25p coins is 100
& no. of 50p coins is 50.
