@ DIPTY SHARMA & VARUN MOTWANI
given that A,B,C COMPLETES WORK IN 15,12,20 DAYS
take the l.c.m of those three i.e 60(total work)
that means A does 4(15*4=60) uints of work a day
similarly B and C do 5 and 3 units a day
C left after 2 days i.e all the 3 worked for 3 days
WORK DONE=(4+5+3)*2=24
WORK LEFT =60-24=36
given that B left 3 before complition of work
INDIRECTLY IT IS GIVEN THAT A COMPLETS THE REMAINING WORK IN 3 DAYS
I.E HE WORKS FOR LAST 3 DAYS
WORK DONE BY A IN LAST 3 DAYS=3(4)=12
WORK LEFT=36-12=24(WORK TO BE COMPLETED BY A AND B)
THAT MEANS A AND B DO 24 UNITS AFTER C LEFT AND BEFORE B LEAVING
LET TIME TAKEN BY THEM BE X
(4+5)*X=24
X=24/9=8/3
TOTAL NUM OF DAYS= 2+(8/3)+3=5+(8/3)=24/3=7.66 DAYS

let work be completed in x days
1 day work of abu,basu,cornel is 1/15,1/12,1/20 respectively
given cornel leaves after 2day so,work done by cornel in 2days=2/20
basu leaves before 3days of completion of work
so,he work for(x-3)days
work done by basu in x-3days=(x-3)/12
abu work for x days
so,work done for x days=x/15
all together complete the work
so,x/15+(x-3)/12+2/20=1
by solving x=23/3=7.66
