A Correct answer
Explanation

7x - 3x = 60 => 4x = 60 => x = 15. A = 7*15 = 105, B = 3*15 = 45.

AI explanation

Let the amounts for A and B be 7x and 3x respectively. The difference between their amounts is 7x minus 3x, which equals 4x. Since the difference is Rs. 60, 4x equals 60, meaning x equals 15. Multiplying this factor by their respective ratio parts, A's amount is 7 times 15, which is Rs. 105, and B's amount is 3 times 15, which is Rs. 45.
