Answer 1

Answer:

59.5253476

Step-by-step explanation:

1 year -> 8%

220days/365days=44/73year ----> $\frac{352}{73}%$%

62,40 --- 100% + $\frac{352}{73}$% = $\frac{7652}{73}$%

Principal? --- 100%

=> P = $\frac{6240 . 100}{\frac{7652}{73} }$= 59.5253476

Given,

Principal(P)= ?

Rate(R)=8%

Time(T)= 15th January to 22nd August,2001 = 220days/365days=44/73

Formula used:  

The compound interest is given by

A= P + $(1+ \frac{R}{100})^{T}$

Where  

A=Amount

P=Principal

R=Rate

T=Time

• Apply the above formula, we get

62.40= $P ( 1 + \frac{8}{100} )^{\frac{44}{73} }$

62.40= P $(\frac{27}{25}) ^ {\frac{44}{73} }$

P =59 .57153138
