Correct Answer: ১.৩৭ টাকা

Explanation:

ধরি, কামাল সপ্তাহে কাজ করে = x ঘণ্টা

কামালের স্বষ্টায় মজুরী= $\frac{১৩৭}{x}$টাকা

ঘণ্টায় মুজুরী ১০% বৃদ্ধি পায়নতুন ঘণ্টায় মজুরী = $\frac{১৩৭}{x}$ + $\frac{১৩৭}{x}$ + ১০%= $\frac{১৫০৭}{১০x}$

সাপ্তাহিক কর্মঘণ্টা ১০% কমার প্রনতুন সাপ্তাহিক কর্মঘণ্টা = x – x x১০%=$\frac{৯x}{১০}$

নতুন সাপ্তাহিক মজুরী= $\frac{৯x}{১০}$ x $\frac{১৫০৭}{১০x}$ = ১৩৫.৬৩

কামালের সাপ্তাহিক মজুরী কমবে = (১৩৭.০০ – ১৩৫.৬৩)= ১.৩৭ টাকা
