Answer 2

Answer:

hey mate here is your answer..

1) Compound interest on 2000 for 3 years is 315.25 the rate of interest is

=> Here, p= rupees 2,000, c. I. =rupees 315.25, n= 3 years

A = P + c.i. = 2,000+315.25

= 2,315.25

Also. A = P (1+ R/100)n

: . 2,000(1+ R/100)³ = 2,315.25

= 2,31,525/100

: . (1+R/100)³ = 2,31,525/2,00,000

= 9,261/8,000 = 21*21*21/20*20*20 = (21/20)³

verification

=> 1+R/100 = 21/20. => R/100 = 21/20

- 1 = 1/20

=> R = 1/20*100% = 5 %

the answer is = 5%
