Rs. 2400 become Rs. 2696.64 in 2 years?​

Answer 1

Answer:

heat do you mean I am not getting

Answer 2

Answer:

6 % p.a.

Step-by-step explanation:

Principal = Rs 2400

Rate = Rs 2696.64

Time = 2 yrs

Rate = x % (let )

Amount = P (1 + r /100) ^ t

2696.64 = 2400 ( 1 + x / 100 )^2

2696.64 / 2400 = (1+ x / 100)^2

By dividing the values by 100 on left hand side ,

269664/240000 = (1+x/100)^2

2809 / 2500 =( 1+x /100)^2

(53 / 50 )^2 = (1+ x / 100 )^2

53 / 50 = 1+ x / 100

53 / 50 - 1 = x / 100

3 / 50 = x / 100

x = 3/50 × 100

x = 6

Therefore , Rate % = 6 % p.a.
