Divide 15 into 2 equal parts such that the sum of their reciprocals would be 3/10(3 by 10)

Answer» Let the nos be x and yThen x+y= 15 》y=15-xAnd
You should take the two part of fifteen = x and (15-x) hence the equation of this condition was 1/x+1/15-x=3/10
Let one be xOther be y X+Y=151/x+1/Y=160X+y/xy=160
