1. 13.5

2. 11

3. 12

4. 14.5

Let Ram do x unit of work each day, working with his full efficiency.

So work done by him in last ten days ( when his efficiency dropped by 30% ) = 0.7 *10x = 7x

Had he worked with his full efficiency he must have done 9x unit work in last 9 days , thus Ganesh must have done (9x -7x = 2x) work on 17th day.

Thus ratio of efficiency of Ram and Ganesh = 1:2

So total work = 16×(x+2x)=48x

Work remaining after 7 days = 48x-7×3x=27x

Time taken by Ganesh to complete this work = 27x/2x=13.5
