Solution

Let ₹ x be the amount donated in a Relief fund by Subramaniam.

Then, the amount donated by Naidu will be ₹ (x + 125).

According to the question,

x + x + 125 = 975

⇒ 2x = 975 – 125  ...[Transposing 125 to RHS]

⇒ 2x = 850

⇒ x = ₹ 425   ...[Dividing both sides by 2]

Hence, the amount of money donated by Subramaniam is ₹ 425.
