A person 3

A person distributes his pens among four friends A, B, C and D in the ratio 1/3 : 1/4 : 1/5 : 1/6.

What is the minimum number of pens that the person should have?

Correct answer:

n =  57

Step-by-step explanation:

3 ...  prime number 4=22 5 ...  prime number 6=2⋅3 LCM(3,4,5,6)=22⋅3⋅5=60  d=LCM(3,4,5,6)=60  d1​=d/3=60/3=20 d2​=d/4=60/4=15 d3​=d/5=60/5=12 d4​=d/6=60/6=10  r = d1​:d2​:d3​:d4​ r = 20:15:12:10  n=d1​+d2​+d3​+d4​=20+15+12+10=57
