Answer 1

$\huge \mathbb{Question}$

A circular field has a circumference 360km. Three cyclists starts together and can cycle 48, 60 and 72 km a day round the field. When will they meet?

$\huge \mathbb{Answer}$

▶Speed of first, second and third cyclist are 48 km/day, 60 km/day and 72 km/day. In terms of km/hr,

48 km/day = 48/24 km/h = 2 km/h

60 km/day = 60 km/24 h

72 km/day = 72/24 km/h = 3 km/h

Time = Distance/Speed

Time for 1st cyclist = 360/2 = 180 hrs

Time for 2nd cyclist = 360/(60/24) = 144 hrs

Time for 3rd cyclist = 360/3 = 120 hrs

L.C.M of 180, 144, 120 = 720 hrs

Total Time taken in days = 720/24 = 30 days

Answer : 30 days
