Hence we can safely apply the ratios of the chart to the income directly in part D too. and the answers come out 1440.

But we can't treat C and D separately. Because C & D on their own don't give us the whole information required to calculate the questions asked in C and D part.
For example, in C part we are given the utilities expenditure (11600) only, and are asked to calculate the total expenditure. Total expenditure that represents the whole pie chart. For calculating that we need value 8/100 from the pie chart. So this part is not independent of the pie chart. P.s the amount of total expenditure 145000 (calculated in the C part) matches up with the pie chart. You calculate any expenditure out of 145000, you get the exact same %age value given in the pie chart. This part is fine.

Now for the D part we are only given the breakup of 'other' in ratio 3:4:1. To calculate 'other' we have to go back to the pie chart to get the 16% value of other, so we could calculate savings from 'other'. Hence this part is not independent of the pie chart either. Now if we are taking 16% from the pie chart_which represents 16% of 145000 ((total expenditure) and not 16% of income_ why are we not calculating it accordingly in the D part, that is 16/100* 145000 ? Because in that case figure would match up with the given pie chart.
Can't it be that 24000 is just given as distraction?
