Given:
A man has Rs. 100 in Rs. 1 coins and 50 paise coins.
The worth of the 50 paise coins are same as that of the 1 rupee coins.
To find:
How many coins of each he has?
Solution:
Let's assume,
"x" → the no. of 1 rupee coins
"y" → the no. of 50 paise coins
Since the amount of 1 rupee coins is same as the amount of 50 paise or Rs. 0.50 coins, so we can form an equation as,
x = 0.5y ..... (i)
Also, the man has a total amount of = Rs. 100
Therefore, the equation will be:
x + 0.5y = 100
on substituting the value of x from (i), we get
⇒ 0.5y + 0.5y = 100
⇒ 1y = 100
⇒ y = 100
Substituting the value of y = 100 in (i), we get
x = 0.5y = 0.5 × 100 = 50
Thus, the man has:
50 → no. of 1 rupee coins
and
100 → no. of 50 paise coins.
