A) 21, 24
B) 21, 28
C) 18, 24
D) 21, 25
Correct Answer: A
Solution :
We have, \[\frac{3}{4}=\frac{x}{28}\Rightarrow \frac{3\times 7}{4\times 7}=\frac{x}{28}\] \[\Rightarrow \frac{21}{28}=\frac{x}{28}\] \[\Rightarrow x=21\] Also, \[\frac{3}{4}=\frac{y}{32}\Rightarrow \frac{3\times 8}{4\times 8}=\frac{y}{32}\Rightarrow \frac{24}{32}=\frac{y}{32}\] \[\therefore y=24\]
