A company paid Tk. 500,000 in merit raises to employees whose performance were rated A, B, or C. Each employee rated A received twice the amount of the raise that was paid to each employee rated C, each employee rated B received 1.5 times the amount of the raise that was paid to each employee rated C. If 50 workers were rated A, 100 were rated B, and 150 were rated C, how much was the raise paid to each employee rated A?

Question

Accepted Answer

সঠিক উত্তর: । ব্যাখ্যা: Let, rated C employee রা প্রত্যেকে পেয়েছে $x$ taka. Rated A employee রা প্রত্যেকে পেয়েছে $2x$ taka. Rated B employee রা প্রত্যেকে পেয়েছে $1.5x$ taka. Total money $(50 \times 2x) + (100 \times 1.5x) + (150 \times x) = 100x + 150x + 150x = 400x$. Given $400x = 500000$. So, $x = \frac{500000}{400} = 1250$ taka. Rated A employee রা প্রত্যেকে পেয়েছে $2x = 2 \times 1250 = 2500$ taka.
