Answer:
36days
Step-by-step explanation:
total days is 24 when the work is done together from the start
admi is A and ladka is B
let work % of A be x and B be y
(x+y)*24=100 .....since total percentage is always summed up to 100
6x+x(20)+y(20) =100 .... A worked 6days alone then worked for 20days(26-6) together...total percentage is 100
solving these 2 linear equations we get the result
the y=(25/9)
therefore B does (25/9) part of work out of 100
so to find no. of days he takes to finish it alone...consider f as the required variable
(25/9)*f=100
f=36days
