Here's your answer!!
_______________________
Let's first clear this, here p is “paise”.
Total money = ₹29
Now, let the number of 50 paise coins be x and the number of 20 paise be (76 - x).
According to the situation,
50x + 25(76 - x) = 2900 paise (₹29)
∴ 50x + 1900 - 25x = 2900
∴ 25x = 2900 - 190
∴ 25x = 1000
∴ x = 1000/25
∴ x = 40
Therefore, the number of coins of 50 paise is 40 and the the number of coins of 25 paise is (76 - 40) = 36.
