A. Rs. 1225

B. Rs. 1270

C. Rs. 1245

D. Rs. 1250

Answer: Option D

Solution(By Examveda Team)

Let the sum be Rs. x
$$\eqalign{ & \therefore 1352 = x{\left( {1 + \frac{4}{{100}}} \right)^2} \cr & \Rightarrow 1352 = x{\left( {1 + \frac{1}{{25}}} \right)^2} \cr & \Rightarrow 1352 = x{\left( {\frac{{26}}{{25}}} \right)^2} \cr & \Rightarrow x = \frac{{1352 \times 25 \times 25}}{{26 \times 26}} \cr & \Rightarrow x = {\text{Rs}}{\text{.}}\,1250 \cr} $$

    4%= 1/25

    T=2year

    P A
    (25) 2 (26)2
    625 676

    Amount is already given i.e 1352

    Therefore ,

    676= 1352
    1 = 1352/676
    = 2

    Hence ,
    Principal = 2× 625
    = Rupees 1250
