Answer:

2 Years

Step-by-step explanation:

Principle = Rs 2560

Amount with interest = 2890

Rate of interest = 25/4 % Per annum

Time = n Years

A = P (1 + R/100)ⁿ

=> 2890 = 2560 (1  + 25/400)ⁿ

=> 289 = 256 ( 1.0625)ⁿ

=>  ( 1.0625)ⁿ = (289/256)

=>  ( 1.0625)ⁿ = (17/16)²

=> ( 1.0625)ⁿ = (1.0625)²

=> n = 2

Time = 2 Years

in 2 years RS 2560 will raise to RS 2890 at 25/4% p.A
