Question

What is the simple interest on Rs 650 for 3½ years at 4 percent .​

Answer 1

Answer:

4

Step-by-step explanation:

Principal = Rs. 650

Amount = Rs. 741

Time = years and 6 months = 3.5 years

Using the given information we get

Interest= Amount-Principal=741-650=91Interest=Amount−Principal=741−650=91

Formula of simple interest:

I=\dfrac{P\times r\times t}{100}I=

100

P×r×t

where, P is principal, r is rate of interest, t is time in years.

91=\dfrac{650\times r\times 3.5}{100}91=

100

650×r×3.5

91=\dfrac{2275r}{100}91=

100

2275r

91=22.75r

Divide both sides by 22.75.

\dfrac{91}{22.75}=r

22.75

91

=r

4=r
