Question

The average of two numbers is k. if one number is 4 more than three times the other number. what is the value of least number in terms of k?

Answer 1

let one no. be x

then other no. be 3x+4

here avg given is k

so, x+(3x+4)/2=k

=>4x+4/2=k

=>2x+2=k

=>x+1=k/2

=>x=k/2+1

=>x=k+2/2

least no. will be k+2/2
