The answer is £140

First you find 20% of 1200 (which is basically 20 times 12) which gives you £240.

You add £240 to £1200 which is £1440

Then you take £300 off £1440 since he already paid the deposit.

That leaves you with £1140

1140 divided by 10 is 114

However, that will not be sufficient as neither the level of significance nor confidence level is clearly mentioned in the question and thus, we can not answer it without additional information.
