Step-by-step explanation:

A + B = 72 days

B + C = 120 days

C + A = 90 days

LCM of 72, 120, 90 is 360.

efficiency of A + B = 5

efficiency of B + C = 3

efficiency of C + A = 4

2 × (no of days taken by A + B + C )= 360 / (5+3+4)

2 × (no of days taken by A + B + C ) = 360 / 12

no of days taken by A + B + C = 30 /2

no of days taken by A + B + C = 15
