Total work =8
One day work ram and shyam 1/8
Work done in 3 days 3/8
Remaining work 5/8
Time taken by shyam to finish remaining = 15 days
shyam can finish whole work = 15*8/5= 24
hence
we know that both can do work in 8 days shyam alone can do in 24 days
let ram can do it in x days
then acc to question
1/x +1/24 = 1/8
1/x=1/8 - 1/24
1/x=1/12 (((((TAKING LCM AND SOLVING)))))
SO X=12 DAYS
HENCE RAM CAN DO IT IN 12 DAYS
