Answer 2

Answer:

60

Step-by-step explanation:

A:B:C

6:5:4

Let's suppose number be x

If we add 15to each number then,

6x+15: 5x+15: 4x+15

15: 13: 11

so, 6x+15/5x+15 = 15/13

then by cross multiplying

78x + 195 = 75x + 225

After solving the equation, we get:

x = 10

and number A = 10*6 = 60
