Question
A person distributes pens among his three friends A, B
and C in the ratio 1/5 : 1/6: 1/8 . What is the minimum number of pens that the persons should have?Solution
A : B : C = 1/5 : 1/6: 1/8 = 1/5 × 120 : 1/6 × 120 : 1/8 × 120[ LCM ] = 24 : 20 : 15 ∴ Minimum number of pens = 24 + 20 + 15= 59
