Let the salaries be 4x and 7x
Therefore,
5(4x + 25) = 3(7x + 25)
20x + 125 = 21x + 75
x = 50
Therefore, their salaries are 4(50) & 7(50) i.e., 200 & 350

Answer:
Step-by-step explanation:
Let their salaries be 3x and 5x.
According to the question,
(3x + 20) ÷ (5x + 20) = 13/21
21 (3x + 20) = 13 (5x + 20)
63x + 420 = 65x + 260
420 - 260 = 65x - 63x
160 = 2x
x = 80
3x = 3×80 = 240
5x = 5×80 = 400
Therefore, the respective salaries are Rs. 240 and Rs. 400
