2pipes can fill a cistern in 3 minutes. if the larger pipe takes 4 minutes lesser than the smaller pipe to fill the cistern, how much time does the smaller pipe take to fill the cistern?

Let the time taken by 1st pipe be x time taken by 2nd pipe=x-4 cistern filled by 1st pipe in 1min is 1/x cistern filled by 2nd pipe in 1min is 1/x-4 1/x-4+1/x=1/3 x+x-4/x(x-4)=1/3 3(2x-4)=x^2-4x 6x-12=x^2-4x

answer:
