Find the whole number which when decreased by 20 is equal to 69times the reciprocal of the number.
Answered by admin @
Let the number be x. thenx - 20 = 69/x .
[reciprocal of x will be 1/x]
if we solve it then we get the following quad equation.
x2 - 20x - 69 = 0
x2 - 23x + 3x - 69 = 0
x(x - 23) + 3 (x - 23) = 0
thus, x = 23 , -3.
