Question

) A certain amount was deposited into a bank account having an interest rate of 5%.
If the total amount after 4 years was 1,500, how much was the amount deposited
initially? For the same initial amount, how should the interest rate increase such
that the simple interest would amount to 400?​

Answer 1

Answer:

1250 /-

Step-by-step explanation:

Amount = Principal + Interest

SI = $\frac{PRT}{100}$

So, SI = $\frac{P*4*5}{100}$ = $\frac{P}{5}$

Therefore, the amount will be = $\frac{6P}{5}$ = 1500

So, P = 1250 Rupees....
