"Let the total units of work be LCM(15,25)=75
"A does 75/15 = 5 units per day work
"B does 75/25 = 3 units per day work
"Together they do (5+3)=8 units of per day work.
"Let say both of them worked for x days.
"Work done by them in x days = 8x
"Remaining work = 75–8x
"This remaining work done by A alone in 3 days.
"Hence,
"3*(A's work per day)= 75–8x
"3*5 = 75-8x
"x=60/8 = 7.5 days
"Total number of days taken to complete the work = 7.5+5 = 12.5 days
