Q1 A+B=3
B+C=9
A+C=12
LCM( total work)= 36
one day work A+B 12, B+C=4,A+C=3
A+B+B+C+C+D=19
2(A+B+C)=19
A+B+C=9 1/2
I don't knw correct or not
Q2 A:10
B:15
LCM= 20 then one day work A=3, B=2
work together for 2 days =5×2=10
remaining work completed by B = 2×D = 20
D= 10 days
total time 12 days

first wrong :
2(A+B+C) = 19
A+B+C = 19/2
TOTAL WORK = 36
TIME = 36/19/2
72/19 DAYS
second is correct

sanukumar ... Jo 19/2 hai Apne wo work/day nikala hai... to find out time you have to divide it further by 36 ( which was LCM of 3,9,12) ..answer is correct in your book
