Question. 72
Subramaniam and Naidu donate some money in a Relief Fund. The amount paid by Naidu is ₹125 more than that of Subramaniam. If the total money paid by them is ₹975, find the amount of money donated by Subramaniam.
Answer:
₹425
Detailed Answer with Explanation:
Let Subramaniam = x, then Naidu = x + 125.
x + (x + 125) = 975 ⇒ 2x + 125 = 975 ⇒ 2x = 850 ⇒ x = 425.
