প্রশ্নে বলা হচ্ছে, একজন গাড়ী ব্যবসায়ীর কিছু গাড়ি আছে। গাড়িগুলোর মধ্যে অর্ধেক কালো এবং বাকি গাড়িগুলো সমপরিমাণে নীল, সাদা এবং লাল। আগামী মাসে কালো গাড়ির 70 শতাংশ, নীল গাড়ির ৪০ শতাংশ, সাদা গাড়ির 30 শতাংশ এবং লাল গাড়ির 40 শতাংশ বিক্রয় করা হবে । প্রশ্ন হলো আগামী মাসে কত শতাংশ গাড়ি বিক্রয় করা হবে?Let, total number of cars = x∴ The number of black cars

= x2∴ The remaining number of cars = x-x2 = x2∴ The number of blue car = x2 ×13 = x6 [As, they are same in amount]∴  The number of white car = x2 ×13 = x6∴  The number of red car = x2 ×13 = x6Now, the number of black cars that are sold = x2 of 70% = 7x20∴ The number of blue cars that are sold =x6 of 80% = 2x15∴ The number of white cars that are sold =x6 of 30% = x20∴ The number of red cars that are sold =x6 of 40% = x15∴  The total number of cars that are sold =7x20 + 2x15+x20 + x15 = 36x60 = 3x5∴  Percentage of cars that are sold = 3x5x× 100% = 3x5 × 1x× 100% = 60%
