 Pinnacle  Day: 79th - 81st  Simple Interest 
 Simple Interest 
 Key Points:- 
 1.  Simple  Interest  on  a  sum  (principal)  of 
 money  at  R%  per  annum  for  T  years  is 
 given by: 
 ???? =
 ??????????????????     ×     ????????     ×     ???????? 
 100 
=
 ?????? 
 100 
 2.  Amount ( A ) = Principal + S.I. 
 3.  Also,  ,  ,  ?? =   
 ????     ×     100 
 ??     ×     ?? 
 ?? =   
 ????     ×     100 
 ??     ×     ?? 
 ?? =
 ????     ×     100 
 ??     ×     ?? 
 Example:  A  man  lends  Rs.  500  at  10% 
 per  annum  for  2  years.  His  interest  will 
 be: 
 Solution:  Here,  P  =  Rs.  500,  R  =  10%  and 
 T = 2 years. 
 ???? =
 ?????? 
 100 
=
 500     ×     10     ×     2 
 100 
= ???? .    100 
 Important Note : 
 1)  Notice  that  in  the  formula,  ,  ???? =
 ?????? 
 100 
 we are just calculating  of P .  ??     ×     ?? ( ) % 
 2)  Simple  Interest  increases  linearly  with 
 the  number  of  years  i.e.  to  get  SI  for  1 
 year  ,you  can  directly  divide  given 
 interest by the number of years. 
 Example:  If  SI  is  Rs.  400  for  4  years,  then 
 it will be Rs. 200 for 2 years. 
 3)  Annual Installment in case of SI 
 = 
 100  ??    
 100  ??    +   
 ???? (    ??    -    1 )

 Pinnacle  Day: 79th - 81st  Simple Interest 
 Simple Interest 
 Key Points:- 
 1.  Simple  Interest  on  a  sum  (principal)  of 
 money  at  R%  per  annum  for  T  years  is 
 given by: 
 ???? =
 ??????????????????     ×     ????????     ×     ???????? 
 100 
=
 ?????? 
 100 
 2.  Amount ( A ) = Principal + S.I. 
 3.  Also,  ,  ,  ?? =   
 ????     ×     100 
 ??     ×     ?? 
 ?? =   
 ????     ×     100 
 ??     ×     ?? 
 ?? =
 ????     ×     100 
 ??     ×     ?? 
 Example:  A  man  lends  Rs.  500  at  10% 
 per  annum  for  2  years.  His  interest  will 
 be: 
 Solution:  Here,  P  =  Rs.  500,  R  =  10%  and 
 T = 2 years. 
 ???? =
 ?????? 
 100 
=
 500     ×     10     ×     2 
 100 
= ???? .    100 
 Important Note : 
 1)  Notice  that  in  the  formula,  ,  ???? =
 ?????? 
 100 
 we are just calculating  of P .  ??     ×     ?? ( ) % 
 2)  Simple  Interest  increases  linearly  with 
 the  number  of  years  i.e.  to  get  SI  for  1 
 year  ,you  can  directly  divide  given 
 interest by the number of years. 
 Example:  If  SI  is  Rs.  400  for  4  years,  then 
 it will be Rs. 200 for 2 years. 
 3)  Annual Installment in case of SI 
 = 
 100  ??    
 100  ??    +   
 ???? (    ??    -    1 )

 Where,  A  =  Amount  borrowed,  t  =  Time 
 period (number of installment), 
 r = Interest rate

 Pinnacle  Day: 79th - 81st  Simple Interest 
 Simple Interest 
 Key Points:- 
 1.  Simple  Interest  on  a  sum  (principal)  of 
 money  at  R%  per  annum  for  T  years  is 
 given by: 
 ???? =
 ??????????????????     ×     ????????     ×     ???????? 
 100 
=
 ?????? 
 100 
 2.  Amount ( A ) = Principal + S.I. 
 3.  Also,  ,  ,  ?? =   
 ????     ×     100 
 ??     ×     ?? 
 ?? =   
 ????     ×     100 
 ??     ×     ?? 
 ?? =
 ????     ×     100 
 ??     ×     ?? 
 Example:  A  man  lends  Rs.  500  at  10% 
 per  annum  for  2  years.  His  interest  will 
 be: 
 Solution:  Here,  P  =  Rs.  500,  R  =  10%  and 
 T = 2 years. 
 ???? =
 ?????? 
 100 
=
 500     ×     10     ×     2 
 100 
= ???? .    100 
 Important Note : 
 1)  Notice  that  in  the  formula,  ,  ???? =
 ?????? 
 100 
 we are just calculating  of P .  ??     ×     ?? ( ) % 
 2)  Simple  Interest  increases  linearly  with 
 the  number  of  years  i.e.  to  get  SI  for  1 
 year  ,you  can  directly  divide  given 
 interest by the number of years. 
 Example:  If  SI  is  Rs.  400  for  4  years,  then 
 it will be Rs. 200 for 2 years. 
 3)  Annual Installment in case of SI 
 = 
 100  ??    
 100  ??    +   
 ???? (    ??    -    1 )

 Pinnacle  Day: 79th - 81st  Simple Interest 
 Simple Interest 
 Key Points:- 
 1.  Simple  Interest  on  a  sum  (principal)  of 
 money  at  R%  per  annum  for  T  years  is 
 given by: 
 ???? =
 ??????????????????     ×     ????????     ×     ???????? 
 100 
=
 ?????? 
 100 
 2.  Amount ( A ) = Principal + S.I. 
 3.  Also,  ,  ,  ?? =   
 ????     ×     100 
 ??     ×     ?? 
 ?? =   
 ????     ×     100 
 ??     ×     ?? 
 ?? =
 ????     ×     100 
 ??     ×     ?? 
 Example:  A  man  lends  Rs.  500  at  10% 
 per  annum  for  2  years.  His  interest  will 
 be: 
 Solution:  Here,  P  =  Rs.  500,  R  =  10%  and 
 T = 2 years. 
 ???? =
 ?????? 
 100 
=
 500     ×     10     ×     2 
 100 
= ???? .    100 
 Important Note : 
 1)  Notice  that  in  the  formula,  ,  ???? =
 ?????? 
 100 
 we are just calculating  of P .  ??     ×     ?? ( ) % 
 2)  Simple  Interest  increases  linearly  with 
 the  number  of  years  i.e.  to  get  SI  for  1 
 year  ,you  can  directly  divide  given 
 interest by the number of years. 
 Example:  If  SI  is  Rs.  400  for  4  years,  then 
 it will be Rs. 200 for 2 years. 
 3)  Annual Installment in case of SI 
 = 
 100  ??    
 100  ??    +   
 ???? (    ??    -    1 )

 Where,  A  =  Amount  borrowed,  t  =  Time 
 period (number of installment), 
 r = Interest rate
