Here M1 = 30, D1 = 16,
T1 = 9, M2 = 36 and T2 = 8
By formula, M1D1T1 = M2D2T2
30 x 16 x 9 = 36 x D2 x 8
∴ D2 = (30 x 16 x 9)/(36 x 8) = 15 days

Explanation

Let the principal be Rs. P. 
According to the question,
∴270.40=P(1+1004​)2 
⇒270.40=P(1+0.04)2
⇒P=1.04×1.04270.40​ = Rs. 250
Hence, the principal is Rs. 250.

Explanation

Given, A= Rs.9680,T=2 years,R=12%

∵A=P(1−100R​)
9680=P(1−10012​)2

9680=P(10088​)2
P=9680×2225​×2225​
= Rs. 12,500
