Question

Find the rate when Principal=4000,SI=5000 and time =25 years.......​

Answer 1

Answer:

5%

Step-by-step explanation:

SI=PTR /100

5000 = 4000*25*R /100

5000*100= 100000R

R= 500000/100000

R = 5%

Answer 2

S O L U T I O N :

Given :

• Principal, (P) = Rs.4000
• Simple Interest, (SI) = Rs.5000
• Time, (T) = 25 years

Explanation :

As we know that formula of the Simple Interest:

• S.I. = PRT/100

According to the question :

➣ S.I. = Principal × Rate × Time/100

➣ Rate = S.I × 100/P × T

➣ Rate = 5000 × 100/4000 × 25

➣ Rate = 500/100

➣ Rate = 5%

Thus,

The rate of the Interest will be 5% .

More formulas make :

• Time = S.I × 100/P × R
• Principal = S.I × 100/R × T
• S.I. = PRT/100
