Question

in how many years will rs 300 smount to rs 405 at 5 percent

Answer 1

In 4 years RS 300 amount to RS 405 at 5 percent

Answer 2

Answer:

p = ₹300

p + i = ₹405

i = ₹405 - ₹300 = ₹105

r = 5%

So, as we know,

   i = (p*r*t) / 100

⇒ 105 = 300*5*t / 100

⇒  105 = 15*t

⇒  105 / 15 = t

⇒  7 = t

∴ t = 7
