25=P×29×5100×4×2⇒P=2356
25×100×4×229×5⇒P=235625×100×4×229×5×100⇒P=235625×4×229×5⇒P=8125×4×25⇒P=1625×8⇒P=Rs 13000ii) Let P be the principalWe know,Amount=SI+P⇒11300=PRT100+P⇒11300=P×4×13100×4+P             
[3yrs 3months=3+312=3+14=12+14=134years]⇒11300=P×13100+P  ⇒11300=13P+100P100⇒1130000=113P⇒P=1130000113  ⇒P=Rs 10000
