REBATE IN OLD AND NEW REGIME

One of my friend (Sr. citizen) having a total income from sal+FDr int+Div is Rs. 657232 (after std ddn Rs.50000) and Rs.632232 (after std ddn Rs.75000). His total deductions under chapter VI-A is Rs.233730. He is also having STCG on shares Rs.177808. So his total income in old regime will be Rs.423502+177808. In new regime total income will be Rs.632232+177808. Will he get rebate under sec 87A in old and new regimes. Kindly give me how much tax he has to pay in old and new regimes.
