Answer:
A can finish the work in 45 days alone
Step-by-step explanation: A + B = 15
B + C = 20
C + A = 30
----------------------
2(A + B + C) = 65 (ADD ALL OF THEM)
----------------------
WORK DONE BY A = TOTAL WORK - WORK DONE BY B AND C
A = 65 - 20
WORK DONE BY A = 45
HOPE IT HELPS!!!

Answer:
2(A+B+C) = 1/15+1/20+1/30
TAKE LCM OF 15,20,30 IS 60
A+B+C = 4+3+2
60×2
A+B+C =. 9
120
A= 9/120 - 1/20
= 9 - 3
120
= 6/120
= 20 days ans.
