Adjustment of stcl against ltcg

Hi

I sold a plot of land after holding it for more than three years and I made a capital gain of 15 lakhs and total sale value is 50 lakhs. I am planning to buy a flat with this money which will cost 45 lakhs. During last year I made a short term capital loss of 3 lakhs on shares.

To reduce tax liability I can utilize sec 54F. My question is can I offset the short term capital loss against the long term capital gain and still utilize section 54F

Thanks
