Answer:
it took a person to complete a work in 10 days ,one person 15 days and the other person 30 days
A=10 days
b=15days
c=30days
a and b took leave for 4 days and 3 days respectively
so,a took 10 days right so 10-4= 6
he worked for 6 days and the rest he took leave
then,b took 15 days right so 15-3=2
he worked for 15 days and rest he took leave
so the leave days will be extra
THEN 6+2 DAYS EXTRA TO COMPLETE THE WORK ,
THAT IS =8 DAYS
pls make me brainliest
