If (a + b) : c = 6 : 5, (b + c) : a = 9 : 2, then (a + c) : b = ?

7 : 4 8 : 3 6 : 5 8 : 1

7 : 4

In these type of questions always note that the total amount/ratio must be same in all conditions. ⇒ (a + b) : c = 6 : 5  = 11 (total) ⇒ (b + c) : a = 9 : 2 = 11 (total) total equal is already equal, Therefore, a = 2, c = 5 & b = 11 -(2 +5) = 5 Here, ⇒ (a + c) : b = 7 : 5
