Solution :
Given :
Principal amount, P = Rs. 1000
Time period = 12 months
The maturity value = Rs. 12,715
We know that,



SI = 65 R
So we know,
maturity value = principal amount + SI
12715 = 1000 + 65 R
65 R = 12715 - 1000
65 R = 11715
R = 18%
So the rate is 18%
From the second figure it can be seen that 25 + 144 = 169
This implies that 5^2 + 12^2 = 13^2
This is a right triangle with legs of 5 and 12 and hypothenus of 13.
