Question
Some amount was divided among A, B and C in the ratio
2:5:7. If the share of A is 45 less than share of C, then find the 1/3rd of total amount (in Rs).Solution
A : B : C = 2 : 5 : 7 A : B : C = 2x : 5x : 7x => A = C – 45 => 2x = 7x – 45 => x = 9 A + B + C = 2x + 5x + 7x = 14x = 14 × 9 = 126 => 1/3 × 126 = 42
