Formula used: A=P(1+r∕100)t Calculation: Since both get the same amount after their respective periods, we can equate their amounts: P1(1+10∕100)17=P2(1+10∕100)18 ⇒P1(1.1)17=P2(1.1)18 ⇒P1=P2(1.1) Let P2=x P1=1.1x Total Amount =P1+P2 1617=1.1x+x 1617=2.1x ⇒x=1617∕2.1 ⇒x=770 So, P2=₹770 P1=1.1×770=₹847
