1. p=? r=11% t=9/4years a=4491

   I=a-p

   p=(i×100)/r×t

   p={(4491-p)×100×4}/99

   99p=4491×400-400p

   499p=1796400

   p=3600

   I=3600×33/100

   I=36×33

   =1188

   a=3600+1188

   =4788

   R=8%

   A=12122rs

   T=2 years

   Let p=x rs

   Then 12122-x=x*8*2/100

   =>12122=4x/25+x

   =>12122=29x/25

   =>12122*25/29=x

   =>418*25=x

   =>10450=x

   After 2year8month at 9%per annum

   T=8/3year

   R=9%

   P=10450rs

   I=10450*8*9/300

   =10450*24/100

   =250800/100

   =2508rs

   A=10450+2508=12958r

   Let P be the principle amount

   A=P+

   100

   PRT

   4491=P(1+

   4×100

   11×9

   )

   4491=P(1.2475)

   ⇒ P = 3600 Rs.

   SI=

   100

   3600×11×3

   =1188Rs.

   A = 3600 + 1188 = 4788 Rs.
