প্রশ্নে বলা হচ্ছে যে, একটি দৌড় প্রতিযোগিতায় 36টি টিম রয়েছে। দুপুরের মধ্যে মোট টিমের $\frac{4}{9}$ অংশ প্রতিযোগিতা সম্পন্ন করলো এবং অবশিষ্ট টিমের 70% টিম দুপুর 1 টার মধ্যে প্রতিযোগিতা সম্পন্ন করলো। দুপুর 1 টার মধ্যে কতগুলো টিম প্রতিযোগিতা সম্পন্ন করতে পারেনি?

Given that 36 teams are participating in the race

So $36 \times \frac{4}{9} = 16$ 16 team had finished the race by noon

∴ Reaming team = 36 - 16 = 20

∴ Since 70% of the reaming team had finished by one o'clock

So, 20 of 70% $= 20 \times \frac{70}{100} = 14$

∴ The teams had not finished the race by one o'clock = 20 – 14 = 6
