Question

If A, B and C are three rational numbers such that 85C-A0A = 109,425 A+ 85 B - 145, thes the sum of A, B and C is divisible by a 3 b.6 c7 d. 9​

Answer 1

Step-by-step explanation:

If A, B and C are three rational numbers such that 85 C - 340 A = 109, 425 A+ 85 B = 146, then the sum of A, B and C is divisible by a 3 b.6 c 7  d 9​

• • Given equations are  
• •                                   85 c – 340 a = 109 and 425 a + 85 b = 146
• • Now we need to find the sum of a,b and c.
• • So adding both the equations we get
• •                           85 c – 340 a = 109
• •                            85 b + 425 a = 146
• •  Adding both the equations we get
• •          So we get 85 b + 85 c + 85 a = 255
• •                          85 (a + b + c) = 255
• •                   Or a + b + c = 255 / 85
• •                    Or a + b + c = 3
• •                 Now sum will be divisible by 3
