The Ans is "D".....
As middle spring is removed total extension becomes 1.5x (3x/2)
When load is doubled extension also doubles....
So the ans is 3x which is D... If u dont understand anything in this explaination tell me...
Hope this helps..

tip is first do last 5 ques as they are the easiest ones... than do frm 20-28, they r of waves n r easy. these ques wont take much time... after that start frm 1st ques... try to solve a paper like this n see the time consumption... it wil help a lot. trust me...
