Question

The total amount after 3 years is 9200rs and 10000rs after 5 years by simple interest for the some principle and rate. Then the principle and rate of interest are?

Answer 1

Answer:

Principle 8000 Rate of Interest 5%

Step-by-step explanation:

Amount after 3 years is 9200

Amount after 5 years is 10000

difference 2 years = 10000-9200

                               =800

for 2 years 800

for 1 years 800/2=400

for 3 years 400*3=1200

Amount=Principle +Interest

9200=Principle+1200       (for 3 years)

Principle=8000

SI=PTR/100

Time 1 year,Interest 400

400=8000*1*R/100

R=5%
