প্রশ্নে বলা হচ্ছে যে, A এবং B এর Cost হলো দুটি ভিন্ন ভিন্ন Positive পূর্ণসংখ্যা। যদি Type A এর 4 equitie এবং Type B এর 5 equities এর মোট Cost 27 ডলার হয়, তবে Type A এর 2 equities এবং Type B এর 3 equities এর মোট দাম কত হবে?

এটি মূলত MCQ টাইপ Math, এর সহজ সমাধান নিম্নরূপঃ

Here, cost of 4A and 5B equal 27 dollar.

That means, 4A + 5B = 27

Now, if A= 1, then 4A= $4 A = 4 \times 1 = 4$

$∴ 5 B = 27 - 4 = 23,$ Not possible

$I f, A = 2; t h e n 4 A = 4 \times 2 = 8$

$∴ 5 B = 27 - 8 = 19,$ Not possible

$I f A = 3; t h e n 4 A = 4 \times 3 = 12$

$5 B = 27 - 12 = 15$

$∴ B = \frac{15}{5} = 3$

Cost of A and B is 3 dollar.

The cost of $(2 A + 3 B) = (2 \times 3) + (3 \times 3) = 6 + 9 = 15$ dollars. (Answer)
