1. a is greater than b ny 2 and b is greater than c by 10, If (a+b+c) =130, then b+c-a=?
- A. 34
- B. 34
- C. 34
- D. 34
Answer: Option A
Explanation:
Let, c = x ∴b = x + 10 and a = x + 12 Now,a + b + c = 130 = > x + 12 + x + 10 + x = 130 = > 3x = 130 - 22 = 108 ∴x = (108/3) = 36 i.e, c = 36 ∴ b = 46 and a = 48 ∴(b + c) - a = (46 + 36) - 48 = 34 Ans.
