Some amount was divided among A, B and C in the ratio 2:3:5. If the share of A is 30 less than share of C, then find the 1/5th of total amount (in Rs).
A : B : C = 2 : 3 : 5 A : B : C = 2x : 3x : 5x => A = C – 30 => 2x = 5x – 30 => x = 10 A + B + C = 2x + 3x + 5x = 10x = 10 × 10 = 100 => 1/5 × 100 = 20
