Answer 1

Answer:

Amount = 5290

Principle = 4000

S.I.= Amount-Principle

=5290-4000=1290

Rate of interest= 15% p.a.

Therefore, time= S.I.*100/p*r

= 1290*100/4000*15

=43/20= 2whole 3/20

Hence time= 2whole 3/2,

Answer 2

after

1 year the Intrest is 600

as it is compound interest

the Intrest must be added to the original amount to find the 2nd year Intrest

so the principle amount of 2nd year is 4600

finally we get 690 as the Intrest of 2 nd year

so 4600+690=5290

therefore it takes 2 years
