ram+shyam)'s 2 days work = (1/8+1/12) = 5/24
work done in 4 pair of days = (5/24)*4 = 5/6; remaining work = 1-(5/6) = 1/6
work done by ram on 9th day = 1/8; Remaining work = (1/6)-(1/8)= 1/24
On 10th day it is shyam's turn
1/12 work is done by shyam in 1 day
1/24 work is done by shyam in 12*(1/24) = 1/2
total time = (9 + 1/2) day
