Question

Q.5) In how many years will Rs.20,000 amount to Rs.24500 at the rate of interest 5% p.a. O 2 years 6 months 3 years 4 years O 4 years 6 months​

Answer 1

Step-by-step explanation:

S.I = PRT /100

A = P + S.I

=> A = P + PRT/100

=> A = P(1 + RT/100)

= > A/P = 1 + RT/100

=> 24500/20000 = 1 + 5T/100

=> 1+T/20 = 245/200

=> T/20 = 245/200 - 1

=> T = 45×20/200 = 45/10 = 4.5 years

i.e,. 4 years and 6 months.
