Given data :-
- A bag contains 25 paise and 50 paise coins.
- The number of 25 paise coins is three time the number of 50 paise coins.
- The total money is 50 rupees.
Solution:-
Let, number of 25 paise be x & number of 50 paise be y
According to given
→ Number of 25 paise, x = 3y ....[1]
According to given
→ x + y = 50 ....[2]
{From eq. [1]}
→ 3y + y = 50
→ 4y = 50
→ y = 50/4
→ y = 25/2
→ y = 12.5 or 12 & ½
Put value of y in eq. [2]
→ x + y = 50
→ x + 12.5 = 50
→ x = 50 - 12.5
→ x = 37.5 or 37 & ½
Hence, 12 & ½ amount of coin of 25 paise in bag & 37 & ½ amount of coin of 50 paise in bag .
