Detailed Solution
Download Solution PDFমোট আয়তন = 21 লিটার
দুধ-জলের মিশ্রণের 2/3 ভাগ ছিল দুধ,
⇒ দুধের আয়তন = 2/3 × 21 = 14 লিটার
⇒ জলের আয়তন = 21 – 14 = 7 লিটার
এতে 4 লিটার জল যোগ করা হয়,
⇒ নতুন জলের আয়তন = 7 + 4 = 11 লিটার
⇒ মিশ্রণের মোট আয়তন = 14 + 11 = 25
∴ দুধের শতাংশ = 14/25 × 100 = 56%Last updated on Jun 11, 2025
