(প্রশ্নঃ একজন দুধ বিক্রেতার কাছে দুই পাত্র দুধ আছে ।প্রথম পাত্রে ২৫% পানি এবং অবশিষ্ট অংশ দুধ।দ্বিতীয় পাত্রে ৫০% পানি এবং অবশিষ্ট অংশ দুধ ।দুইটি পাত্র থেকে কি পরিমান দুধ নিয়ে মিশালে নতুন দ্রবনে ১২ লিটার দুধ ও পানির মিশ্রন পাওয়া যাবে,যেখানে পানি ও দুধের অনুপাত হবে ৩ঃ৫) ধরি,প্রথম পাত্রে দুধ ও পানির মিশ্রনের পরিমান =x ২য় পাত্রে দুধ ও পানির মিশ্রনের পরিমান= y তাহলে প্রথম পাত্রে দুধ আছে =3/(3+1) x=3/4x ২য় পাত্রে দুধ আছে = 1/(1+1)y=1/2y প্রথম পাত্রে পানি আছে =1/4x ২য় পাত্রে পানি আছে =1/2y শর্তমতে,(প্রথম ও ২য় পাত্রে পানির পরিমান )/প্রথম ও ২য় পাত্রে দুধের পরিমান)=3/5 or, {(1/4)x +(1/2)y}/{(3/4)x+(1/2)y}=3/5 or,{(x+2y)/4}/{(3x+2y)/4} =3/5 or,(x+2y)/(3x+2y)=3/5 or,5x+10y=9x+6y or,10y - 6y=9x-5x or,4y=4x y=x আবার, x+y=12 x+x=12 or.2x=12 ∴ x=6
