Compute tax payable by nanak assuming that he is more than 60 years of age.

The taxability of capital asset gain depending on the type shall be taxed under 112A for listed shares and 112 for others @ 10 and 20% respectively

for lottery it shall be taxed @ flat rate of 30%

the amt deposited into PPF is irrelevant has deductions are not allowed against such incomes

but remember if the capital gain is 112 gains then we can take the benefit of unexhausted basic exemption limit ie 3 lacs
