অর্ধেক পূর্ণ থাকা অবস্থায় একটি পেট্রোল ট্যাংক হতে ৪ গ্যালন পেট্রোল সরিয়ে ফেলা হলো। এখন ট্যাংকের 1/10 অংশ পূর্ণ আছে। ট্যাংকের ধারণ ক্ষমতা কত? ট্যাংকের ধারণক্ষমতার(1/2 - 1/10) = 2/5 অংশ পেট্রোল সরিয়ে নেয়া হয়েছিল। অর্থাৎ, ধারণক্ষমতার 2/5অংশ = 8 গ্যালন ∴ পূর্ণ ধারণক্ষমতা = 8 x (5/2) গ্যালন = 20 গ্যালনRelated questions
