To guarantee that one of each type of soda (orange, cream, and cherry) has been chosen, you need to remove enough sodas to ensure that you have at least 1 of each type.

First, remove 10 orange sodas. Now you have 10 orange, 15 cream, and 7 cherry sodas remaining.

Next, remove 15 cream sodas. Now you have 10 orange and 7 cherry sodas remaining.

Finally, remove 1 cherry soda.

At this point, you will have removed a total of 10 (orange) + 15 (cream) + 1 (cherry) = 26 sodas to guarantee that you have at least one of each type.

Answer: Option A

Explanation:

ধরি, প্রথম বাইকার অতিক্রম করে = 130 km

∴ দ্বিতীয় বাইকার অতিক্রম করে = 300 - 130 = 170 km

আমরা জানি, t = d/v

এখন ধরি, প্রথমজনের গতিবেগ v1 এবং দ্বিতীয় জনের গতিবেগ v2

∴ সময় একই চলে বলে , d1/v1 = d2/v2

বা = 130/v1 = 170/v2

বা v2/v1 = 170/130 = 17/13

v2:v1 = 17:13
