Answer 1

$\bigstar\huge\bf\underline{\underline\red{Answer:-}}$

$\bigstar\bf\underline\blue{Given:-}$

• $\bf Money \ put \ at \ 11 \ percent \ per \ annum$

• $\bf RS \ 4491 \ in \ 2 \ years \ 3 \ months$

$\bigstar\bf\underline\orange{To \ find:-}$

• $\bf The \ amount \ to \ in \ 3 \ years \ at \ the \ same \ rate$

$\bigstar\bf\underline\green{Solution:-}$

$\bf T \ = \ 2 \ years \ 3 \ months \ = 2+\frac{3}{12}=2+\frac{1}{4}=\frac{9}{4}$

$\bf Let \ P \ be \ the \ principle \ amount$

$\bf A \ = \ P \ + \frac{PRT}{100}$

$\bf 4491 \ = \ P(1+\frac{11×9}{4×100})$

$\bf 4491 \ = \ P(1.2475)$

$⇒\bf P \ = \ 3600RS$

$\bf SI \ = \ \frac{3600×11×3}{100}=1188RS$

$\bf Then,$

$\bf A \ = \ P \ + \ SI$

$\bf A \ = \ 3600 \ + \ 1188$

$⇒\boxed{\boxed{\purple{\bf A \ = \ 4788RS}}}$

Answer 2

Answer:

Rate of interest = 11% and Time = 2 yrs 3 months = 2 yrs 3/12 = 2.25 yrs. X = - 449100/- 124.75 = 3600. So the Principal amount is equal to Rs. 3600
