Capital Gain

obviously he would get a deduction of amount invested out of capital gains if the investment is covered u/s 54 .

 he can get deduction u/s 54 F if the total sale consideration is used for purchasing a residential house property with in 3 yrs from the date of sale. 

if he use partial amt then deduction will be allowed partial. such new house should not be sold with in 3 yrs of purchase. 

Depositing an amount in Capital Gains Scheme is not for avoiding tax from CG.It is earmarking that sum for being utilised for investment in specified capital assests.If the individual fails to make required investment within time the amount deposited in the scheme shall be taxed as CG.

Thanks for all replys
