Question

Sangeeta invested 20000 in the ...​

Answer 1

Answer:

10%

Step-by-step explanation:

Let the compound interest be R %

Principal amount or P = Rs. 20000

Amount received or A = Rs. 29282

Time = 4 years

Now, A = p (1 + R/100)^T

⇒ 29282 = 20000 (1 + R/100)^4

⇒ (1 + R/100)^4 = 29282/20000

⇒ (1 + R/100)^4 = 1.4641

⇒ 1 + R/100 = ⁴√1.4641

⇒ 1 + R/100 = 1.1

⇒ R/100 = 1.1 - 1

⇒ R/100 = 0.1

⇒ R = 10 % Per annum
