Question

3. How much money had Mrs Verma deposited in a bank
if she finds that after 3 months, the bank has paid
*281.25 as interest at the rate 4.5% p.a.?​

Answer 1

Answer:

Let, the amount deposited be x.

Now, principal = x.

Time = 3 months = 1/4 year.

Rate of interest = 4.5%

So, by condition,

(x * 1 * 45) / (100 *10 *4) = 28125/100

Or, x*45 = 28125 * 10 * 4.

Or, x = (28125 * 2 * 4) / 9

Or, x = 3125*8 = 25000

Thus, Mrs Verma deposited Rs. 25,000 in the bank.

Answer 2

Answer

Let, the amount deposited be x.

Now, principal = x.

Time = 3 months = 1/4 year.

Rate of interest = 4.5%

So, by condition,

(x * 1 * 45) / (100 *10 *4) = 28125/100

Or, x*45 = 28125 * 10 * 4.

Or, x = (28125 * 2 * 4) / 9

Or, x = 3125*8 = 25000

Thus, Mrs Verma deposited Rs. 25,000 in the bank.
