Question

A lady deposit rs. 6000 at the rate of si 6 .5% per annum in a bank. 6 months later, when the interest rate is increased to 7% per annum, she deposited rs. 8000 more. What interest will she get after 4 years, if si is calculated on the deposited amount?

Answer 1

Step-by-step explanation:

si= ptr/100

6000=p×6 × 7.5

Answer 2

She will get total interest Rs. 4,115 after 4 years.

Step-by-step explanation:

A lady deposited the amount = Rs.6000

Rate of interest = 6.5%

Time = 6 months

$Interest=\frac{P\times r\times t}{100}$

P = principal amount

r = rate of interest

t = time

Now we will calculate 6 months interest of 6000 Rs.

$=\frac{6000\times 6.5\times 0.5}{100}$

= 195 Rs.

Now she deposited 8000 Rs. more at the rate of interest 7% per annum.

So, Principal amount = 8000 + 6000 = 14,000

      rate of interest = 7%

      Time       = 4 years.

$=\frac{14000\times 7\times 4}{100}$

= 3920 Rs.

Total interest = 3920 + 195 = 4,115 Rs.

She will get total interest Rs. 4,115 after 4 years.
