Question: 85% of a number is added to 24, the result is the same number. Find the number?

Solution:
ধরি, সংখ্যাটি = x

প্রশ্নমতে,
85% of x + 24 = x
⇒ (85x/100) + 24 = x
⇒ x - (85x/100) = 24
⇒ (100x - 85x)/100 = 24
⇒ 15x/100 = 24
⇒ 15x = 24 × 100
⇒ x = (24 × 100)/15
⇒ x = 2400/15
⇒ x = 160

অতএব, সংখ্যাটি হলো 160।
