Multiple choice

Three teams in a rowing competition are rowing three boats in the same direction at speeds which are in the ratio 2: 3: 4. What will be the ratio between the times taken by these boats to cover a full channel? तैराकी की प्रतियोगिता में तीन टीमों की तीन नाव एक ही दिशा में 2 : 3 : 4 के अनुपात में नाव खे रही हैं। पूरे चैनल को पार करने में इन नावों द्वारा लिए गए समयों में क्या अनुपात होगा ?

  1. 2 : 3 : 4

  2. 4 : 3 : 2

  3. 4 : 3 : 6

  4. 6 : 4 : 3

D Correct answer
Explanation

Speed ratios are 2:3:4. For a fixed distance, time is inversely proportional to speed. If speeds are in ratio 2:3:4, then times are in ratio 1/2 : 1/3 : 1/4. Converting to integers with LCM 12: 6:4:3. Option A incorrectly uses the same ratio as speed. Options B and C don't represent the inverse relationship correctly.
