Question

In how many years will rs 4000 amount rs 4480 at 6% per annum

Answer 1

Answer:

2 YEARS

Step-by-step explanation:

SI = (P×R×T) / 100

Amount = Principal + Simple Interest

∴Simple Interest = Amount - Principal

Given: Principal(P) = Rs 4000       ;     Amount(A) = Rs 4480    ;

          Rate of Interest(R) = 6% per annum

SI = A - P

∴SI = Rs ( 4480-4000) = Rs 480

Now SI = P×R×T/100

Now substituting the values

480 = 4000×6×T/100

⇒480 = 40×6×T

⇒480 = 240×T

⇒480/240 = T

⇒T=2

∴Time = 2 years...
