If a train runs at 40 kmph, it reaches its destination late by 11 minutes but if it runs at 50 kmph, it is late by 5 minutes only. The correct time for the train to complete its journey is : Correct Answer 19 minutes

Hints: উভয় ক্ষেত্রেই train টি একই দূরত্ব অতিক্রম করে। তখন বেগ kmph এ দেওয়া কিন্তু সময় দেওয়া মিনিটে। এই kmph এর মানকে 60 দ্বারা ভাগ করে মিনিটে নিতে হবে। ধরি, original time t. প্রথম ক্ষেত্রে দূরুত্ব = বেগ × সময় = 40 /60 (t + 11) দ্বিতীয় ক্ষেত্রে, দুরুত্ব = 50/60 (a + 5) এখন, 40/60(t + 11) = 50/60 (t + 5) t = 19 minutes
