Hey !!!

(A + B )'s work in ONE DAY = 1/20 ---1)
(B + C ) 's work in one day = 1/30 ----2)
(C + A ) 's work in one day = 1/40------3)

Adding thrice EQUATION

we get ,

(A + B + B + C + C + A ) = 1/20 + 1/30 + 1/40

2( A + B + C ) = 13/120

(A + B + C )'s work in one day = 13/240

A's alone work = 13/240 - 1/30 = 5/240 = 1/48

since A's alone work = 48days

SIMILARLY .
for B's alone work = 13/240 - 1/40 = 7/240 days

since B's alone work = 34 + 2/7 days

And finally

c's alone work = 13/240 - 1/20 = 1/240

c's alone work = 240days
