ধরি ট্যাংকের ধারণক্ষমতা = x লিটার প্রথমে ট্যাংক 1/3 ভরা ছিল অর্থাৎ প্রথমে = (1/3)x লিটার ছিল m লিটার যোগ করার পর ট্যাংক 7/9 ভরা হল অর্থাৎ শেষে = (7/9)x লিটার হল এখন, (1/3)x + m = (7/9)x ⇒ m = (7/9)x - (1/3)x ⇒ m = (7/9 - 1/3)x ⇒ m = (21/27 - 9/27)x ⇒ m = (12/27)x ⇒ m = (4/9)x ⇒ x = (9/4)m সুতরাং ট্যাংকের ধারণক্ষমতা = (9/4)m লিটারRelated questions
