Mr. Zahid 1920 মিটার দীর্ঘ একটা Road 120 দিনে তৈরী করার জন্য একটি চুক্তি করলেন। এজন্য তিনি 160 জন শ্রমিক নিয়োগ করলেন। কিন্তু 24 দিন পর দেখলেন যে, কাজের মাত্র $\frac{1}{8}$ অংশ কাজ সম্পন্ন হয়েছে। এখন তিনি যদি সময়মতো কাজটি সম্পন্ন করতে চান তবে অতিরিক্ত কতজন লোক নিয়োগ করতে হবে?

Given time to complete the task= 120 days & Work already done = $\frac{1}{8}$ Part

Now, after 24 days, remaining time = 120-24= 96 days

& After part work done, remaining task=$\left(1-\frac{1}{8}\right)=\frac{7}{8}$ Part

Now, 24 days are needed to do $\frac{1}{8}$ of the work by 160 workers

1 day is needed to do of the work by $160 \times 24$ workers

1 day is needed to do 1 of the work by $\frac{160\times 24\times 8}{1}$ workers

96 days are needed do$\frac{7}{8}$  of the work by $\frac{160\times 24\times 8\times 7}{1\times 96\times 8}=280$ workers

Additional workers are needed = $280-160=120$ 

10 বছর পর কোনো আসলের সরল সুদ 600 টাকা হবে। 5 বছর পর আসল 3 গুণ হলে 10 বছর পর মোট সুদ কত হবে?

Amount of interest in 10 years = 600 Tk. 

Amount of interest in 1 years = $\frac{600}{10}$ =60 Tk.

In simple interest, the principal is trebled, the interest will also be trebled.

Amount of interest in first 5 years = $5 \times 60 = 300 Tk.$

And the of interest in the next 5 years = $60 \times 5 \times 3 = 900 Tk.$

At the end of tenth total interest will be = $300+ 900= 1,200 Tk.$
