Sum of three positive numbers is 120. If the ratio of
the first and second number is 5:7, respectively while difference between the first and third number is equal to the second number, then find the third number.Solution
ATQ,
Let the first number be '5x' So, second number = 5x X (7/5) = '7x' And, third number = 5x + 7x = '12x' ATQ: 5x + 7x + 12x = 120 Or, 24x = 120 So, x = 5 So, third number = 12 X 5 = 60
