‘To dispose of’ is the correct phrase to be used here. It means to get rid of something by selling or giving. Thus, the correct formation would be, ‘Raman wants to dispose of his house’.

In the given sentence,

Despite is the preposition. It does not take 'of' after it. Therefore, the grammar mistake in the given sentence is 'of'.

Hence, the correct sentence is  "She went to gym despite her illness."

Let the C.P be Rs.100 and S.P be Rs.x, Then
The profit is (x-100)
Now the S.P is doubled, then the new S.P is 2x
New profit is (2x-100)
Now as per the given condition;
=> 3(x-100) = 2x-100
By solving, we get
x = 200
Then the Profit percent = (200-100)/100 = 100
Hence the profit percentage is 100%
