Answer:
50-paisa coins = 9
25-paisa coins = 16
Step-by-step explanation:
Define x:
Let the number of 50-paisa coin be x
Since there is a total of 25 coins
Then the number of 25-paisa coins will be (25 - x)
Solve x:
The total value is 8.50
0.5x + 0.25(25 - x) = 8.50
0.5x + 6.25 - 0.25x = 8.5
0.25x = 2.25
x = 2.25 ÷ 0.25
x = 9
Find the coins:
50-paisa coins = x = 9
25-paisa coins = 25 - x = 25 - 9 = 16
Answer: There are 9 50-paisa coins and 16 25-paisa coins.
then his ans is wrong
then what is ans
Yes, there are 2 types of coins - The 50-paisa coins and the 25-paisa coins.
50-paisa coins = 9
25-paisa coins = 16
Total coins = 9 + 16 = 25 (checked)
50-paisa coins = 9
25-paisa coins = 16
Total coins = 9 + 16 = 25 (checked)
i am also not able to ans isnt there any other detail in the question
but u wrote since there are total of 25 coins
Yes ... it is given that there are 25 coins in total
So if we assumed that there are x number of coins that are 50-paisa, and there is a total of 25 coins, then (25 -x ) coins must be the 25-paisa coins.
no there is no other details
oh ya i didnt read the question properly silly of me
ok
