The ratio of efficiency of a is to c is 5:3.The ratio of no.Of days taken by b is to c is 2:3.A takes 6 days less than c, when a and c completes the work individually.B and c left the work after 2 days. The no of days taken by a to finish the remaining work?

A : B : C
Efficiency 10 : 9 : 6
No of days 9x : 10x : 15x
given=> 15x-9x = 6
hence, x = 1
Number of days taken by A = 9 and daily work done=10
Number of days taken by B= 10 and daily work done=9 (total work =90)
Number of days taken by C = 15 and daily work done=6
work done by B and C in initial 2 days =30
rest work =60
Number of days required by A to finish = 60/10=6 days
