Answer 1

Answer:

19 percent anser question

Answer 2

Answer:

5%

Step-by-step explanation:

the person starts with 10000 deposit

but withdraws 4000 after 2 years so,

let the interest rate be "x"

so x% interest will be charged on 6000 for 5 years .

and x% interest will be charged on 4000 for 2 years . (as it was withdrawn after 2 years)

___________________________________________

therefore,

total interest is,

6000x/100 + 4000x/100.............(1)

and the principal amount which the person will get back is 6000 ( as 4000 was already withdrawn)

therefore, adding equation....(1),

6000 + 6000x/100 + 4000x/100 = 7900

= 300x + 80x = 1900

= 380x = 1900

= x = 5 .

therefore, the interest (simple interest) is

= 5%
