Solution: প্রশ্নে বলা হচ্ছে, 60 লিটারের একটি চিনি ও পানির দ্রবণে 20% চিনি আছে । ঐ দ্রবণে চিনির পরিমাণ 8% করতে কত লিটার পানি যোগ করতে হবে ? দ্রবণে চিনি আছে 20% দ্রবণে পানি আছে = (100 - 20)% = 80% এখন, ঐ দ্রবণে চিনির পরিমান = (60% এর 20%) = 12 লিটার পানি আছে (60 - 12) = 48 লিটার ধরি, দ্রবণে চিনির পরিমাণ 8% করতে x লিটার পানি যোগ করতে হবে । প্রশ্নমতে,

\frac{{48 + x}}{{12}} = \frac{{92}}{8}

[8% চিনি থাকলে দ্রবণে 92% পানি থাকবে ] => 48 + x =

\frac{{92 \times 12}}{8}

= 138 => x = 138 - 48 = 90 x = 90
