রনি ৬ ঘন্টায় টাইপ করে = ৩২ পৃষ্টা

$∴$ রনি ১ ঘন্টায় টাইপ করে = $\frac{৩ ২}{৬} = \frac{১ ৬}{৩}$ পৃষ্টা

আবার, জনি ৫ ঘন্টায় টাইপ করে = ৪০ পৃষ্টা

$∴$ জনি ১ ঘন্টায় টাইপ করে = $\frac{৪ ০}{৫} = ৮$ পৃষ্টা

তারা একত্রে ১ ঘন্টায় টাইপ করে = ( $\frac{১ ৬}{৩} + ৮) = (\frac{১ ৬ + ২ ৪}{৩}) = \frac{৪ ০}{৩}$ পৃষ্টা

এখন, তারা একত্রে $\frac{৪ ০}{৩}$ পৃষ্টা টাইপ করে = ১ ঘন্টায়

$∴$ তারা একত্রে ১১০ পৃষ্টা টাইপ করে = $\frac{৩ \times ১ ১ ০}{৪ ০} = ৮ \frac{১}{৪}$ ঘন্টায় বা ৮ ঘন্টা ১৫ মিনিট।

The prevalence of teenage employment in Bangladesh is controversial. Questions have been raised regarding whether adolescents should work and if they do, what the terms and conditions will be. It is argued that work experience can promote the healthy development of adolescents when it is moderate in intensity and does not interfere with physical and mental growth. According to Bangladesh Labour Act 2006, an adolescent is defined as a person above the age of 14 but below 18. According to the law, before the appointment of a job, ascertainment of the age, birth, school, or registered physician's certificate regarding the age of the adolescent shall be used. After the appointment, some other conditions shall have to be followed regarding working hours, hazardous works, etc. Adolescents shall not be required to work between 7 pm to 7a.m and the working hours shall not be more then 5 hours in a day and 32 hours in a week. In addition, adolescents shouldn't clean, lubricate of adjust any part of machinery in motion. Further, the employment of adolescents on dangerous machines without full instruction, precaution, and sufficient training, is prohibited. However, the proper implementation of existing regulations is questionable. For the smooth physical and mental development of adolescents, the authorities should implement the laws strictly to build up a healthy and prosperous generation.
