Answer:
The number of 50 p coins = 180
Step-by-step explanation:
Given:
- Number of 25 p coins = 2 times number of 50 p coins
- Total money in the piggy bank = Rs. 180
To Find:
- The number of 50 p coins
Solution:
We know that
50 p =0.5 rupees
25 p = 0.25 rupees
Let the number of 50 p coins be x.
Let the number of 25 p coins be y
By given
Number of 25 p coins = 2 times number of 50 p coins
Hence,
y = 2x-----(1)
Given that the total amount in it is Rs.180
Hence,
0.25 × y + 0.5 × x = 180
Substitute the value of x from equation 1
0.25 × 2x + 0.5 × x = 180
0.5 x + 0.5 x = 180
1x = 180
x = 180
Hence the number of 50 p coins is 180
Now to find the number of 25 p coins, substitute the value of x in equation 1
y = 2 × x
y = 2 × 180
y = 360 coins
Hence there are 360 25p coins.
Verification:
Total amount in the piggy bank = 180 rupees
0.25 × 360 + 0.5 × 180 = 180
90 + 90 = 180
180 = 180
Hence verified.
