Answer 2

A sum of 450 amounts to 495 at simple interest in 2 years...

• First we need to find the rate.

• A=P(1+(TR/100))=450(1+(2R/100)

• 495/450=1+(2R/100)

• 0.1=2R/100

• 2R=10

• R=5

• Now the second part of the question:

• A=P(1+(TR/100))

• 943=820(1+(5T/100))

• 1.15=1+(5T/100)

• 0.15=5T/100

• 5T=15

• T=3
