- Let the two numbers are x and y Now according to the question x+y = 14..(1) & 1/x + 1/y = 7/24.. (2)
Now from equation (2) we can write (x+y)/xy = 7/24
so 14/xy = 7/24
so xy = 24/7*14 = 48
Now (x-y)^2 = (x+y)^2-4xy putting the value of x+y and xy we can get x-y = 2
now by solving x+y=14 and x-y = 2 we can get x= 8 & y = 6
