1.	A man wants to reach a centain destination. One-sixth of the total distance is muddy while half the distance is tar road. For the remaining distance he takes a boat. His speed of traveling in mud, in water, on tar road is in the ratio ` 3 : 4 : 5`. The ratio ratio of the durations he requires to cross the patch of mud, stream and tar road isA. `1/2:4/3:5/2`B. `3 : 8 : 15`C. `10 : 15 : 18`D. `1: 2 : 3`
Answer» Correct Answer - C Let distance is 6 x `{:(,,"mud",:,"tar",:,"stream"),("distance",,"x",:,"3x",:,"2x"),("speed",,"3v",:,"5v",:,"4v"),("time",,(x)/(3v),:,(3x)/(5v),:,(2x)/(4v)),(,,10,:,18,:,15):}`
