Explanation: যদি ১০ জন লোক ২৪ ঘন্টায় ১৫টি কেক তৈরি করতে পারে, তাহলে ১ জন লোক ২৪ ঘন্টায় \(\frac{১৫}{১০}\) টি কেক তৈরি করবে। সুতরাং, ১ জন লোক ১ ঘন্টায় \(\frac{১৫}{১০ \times ২৪}\) টি কেক তৈরি করবে। এখন, ৮ জন লোক ১ ঘন্টায় \(\frac{১৫ \times ৮}{১০ \times ২৪}\) টি কেক তৈরি করবে। এবং ৮ জন লোক ৩৬ ঘন্টায় \(\frac{১৫ \times ৮ \times ৩৬}{১০ \times ২৪}\) টি কেক তৈরি করবে। এবার আমরা হিসাব করব: \(\frac{১৫ \times ৮ \times ৩৬}{১০ \times ২৪} = \frac{৫৪৩০০}{২৪০} = ১৮\) টি কেক। সুতরাং, ৮ জন লোক ৩৬ ঘন্টায় ১৮টি কেক তৈরি করতে পারবে।
