Question

how long does it take for a principle of 20 rupees 25000 at a simple interest rate of 5% to become rupees 30000 ​

Answer 1

Answer:

4 years

Step-by-step explanation:

P= ₹25,000

R= 5% per annum

Amount = Principal+Interest

30,000 = 25,000+Interest

Interest = 30000-25000

= ₹5,000

$5000 = \frac{25000 \times 5 \times t}{100}$

$5000 = 250 \times 5 \times t$

$t = \frac{5000}{250 \times 5}$

$\frac{500}{25 \times 5}$

$\frac{100}{25}$

$t = 4$
