Ram can do a piece of work in 8 days which Shyam can finish in 12 days. If they work at it on alternate days with Ram beginning, in how many days, the work will be finished?	Choose the correct choice from the following choices
A) 9 1/3
B) 9 1/2
C) 9 1/4
D) 10 1/3
E) 11 1/3
(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   ANSWER:9 1/2
