Answer 1

Solution:-

You haven't mentioned that whether the charged interest is simple or compound. I have solved it considering as simple and compound both.

As simple Interest :

Let 'P' be the principal.
Then, Simple Interest will Rs. (1416 - P)
Simple Interest = (P*R*T)/100
1416 - P = (P*9.5*5)/100
141600 - 100P = 47.5P
141600 = 47.5P + 100P
147.5P = 141600
P = 141600/147.5
Principal = Rs. 960

As Compound Interest :

A = P(1 + R/100)ⁿ
1416 = P(1 + 9.5/100)⁵
(1416/P) = (109.5/100) × (109.5/100) × (109.5/100) × (109.5/100) × (109.5/100)
Principal = Rs. 900

Answer 2

Answer:

Answer is 960

Step-by-step explanation:

Principal- assume x

R- 9 1/2= 19/2= 9.5

R- 9 1/2= 19/2= 9.5 T- 5 years

R- 9 1/2= 19/2= 9.5 T- 5 yearsI- Rs. 1416

R- 9 1/2= 19/2= 9.5 T- 5 yearsI- Rs. 1416

SI- P×R×T/100

R- 9 1/2= 19/2= 9.5 T- 5 years

I- Rs. 1416

SI- P×R×T/100

SI- x×19×5/100×2

To find x or principal

x= Interest ×100/Rate×Time

x=1416×100/9.5×5

x=141600/47.5+100

x=141600/147.5

x=960

Hence, the principal is 960
