A + B = 1/20 + 1/15 = 7/60 A + C = 1/20 + 1/12 = 8/60 7/60 + 8/60 = 15/60 = 1/4 4 days * 2 = 8 days

question has given that A and C completed the work in 12 days, not only C
NITIKA BALI
A+c together can complete in 12 days so accordingly there one day work is 1/12 ; 7/60+1/12=1/5 5*2=10 days
Rectified . it is A completes work in 12 days not A+C.
