Question

Picture below................................

Answer 1

Answer:0.02 aka 2%

Step-by-step explanation:

2%

Step-by-step explanation:use formula below :

S.I=P×R×T/100

Make the unknown variable subject of the formula

100×S.I/P×T=Rate (R)

R=Rate

S.I =Simple interest

P=principal

T=Time

100×8/200×2=800/400=2%

Answer 2

Answer:

0.08 is the required answer.

Step-by-step explanation:

• Here, the principal, time and simple interest are given to us. We have to find the rate of interest.

Given formula for finding rate,

Rate = Time × $\sf \frac{ Simple\: Interest }{ Principal }$

Where,

• Time = 2 yrs
• Simple Interest = $ 200
• Principal = $8

According to the question :-

Rate = Time × $\sf \frac{Simple \: Interest}{Principal}$.

Substitute the given value of time, simple Interest and principle.

Rate = 2 × 8 / 200

Rate = 16 / 200 = 0.08 %

Hence, the rate of the account is 0.08 .
