Year 2015 Corporation tax  26% Income tax  29.6% Wealth tax  2.6% Customs duty  Excise duty  Service tax  14.8% In 2015, if the amount collected through excise duty was 11.7 crore, which was 50% of corporate tax, what was the amount collected through customs duty? (Ans: 12.6 crore) Note:1 crore mean 10 million. Solution: g = 11.7 f + g = 27% f = 27  13 = 14% 13% = 11.7 14% = ? 11.7 × 14/13 = 12.6 crore How is the value 13 is obtained?

Well, 50% of corporate tax at 26% would do it.

Why does f + g = 27%? This 27% figure seems to appear from nowhere.

We were told that the corporate tax is 26% (of some amount) that "amount" would be 23.4/0.26= 90. The excise tax is 11.7 which is 13% of 90. The taxes so far are 26+ 29.6+ 2.6+ 13+ 14.8= 86%. That leaves 100 86= 14% for "customs duty". Quote:

There's no reason why they should total 100%.
