A. 2 : 5
B. 3 : 7
C. 5 : 3
D. 7 : 3
Answer: Option C
Solution(By Examveda Team)
$$\eqalign{ & {\text{Let}}\,40\% \,{\text{of}}\,A = \frac{2}{3}B \cr & {\text{Then}},\,\frac{{40A}}{{100}} = \frac{{2B}}{3} \cr & \Rightarrow \frac{{2A}}{5} = \frac{{2B}}{3} \cr & \Rightarrow \frac{A}{B} = {\frac{2}{3} \times \frac{5}{2}} = \frac{5}{3} \cr & \therefore A:B = 5:3 \cr} $$Join The Discussion
