Correct Answer - Option 2 : 9%
GIVEN:
C.I = Rs. 752.40
A = Rs. 4752.40
T = 2 years
FORMULA USED:
A = P (1 + R/100)T
CALCULATION:
P = A - C.I
⇒ 4752.40 - 752.40 = Rs. 4000
A.T.Q
4752.40 = 4000 (1 + R/100)2
⇒ 47524/40000 = (1 + R/100)2
⇒ 11881/10000 = (1 + R/100)2
⇒ (1 + R/100) = 109/100
⇒ R/100 = 9/100
⇒ R = 9%
∴ The rate is 9%.
