A. Rs. 20
B. Rs. 21.81
C. Rs. 22
D. Rs. 18.33
Answer: Option D
Solution(By Examveda Team)
S.I. on Rs. (110 - 10) for a certain time = Rs. 10.S.I. on Rs. 100 for double the time = Rs. 20.
T.D. on Rs. 120 = Rs. (120 - 100) = Rs. 20.
$$\eqalign{ & {\text{T}}{\text{.D}}{\text{.}}\,{\text{on}}\,{\text{Rs}}{\text{.}}\,{\text{110}} \cr & = Rs.\,\left( {\frac{{20}}{{120}} \times 110} \right) \cr & = Rs.\,18.33 \cr} $$
