Question
The average of two numbers is 25, and the square root of
their product is 20. What is the difference between the two numbers?Solution
Let the two numbers = a and b         Given – Average of numbers = (a + b)/2 = 25 a + b = 50       ...(I) square root of these numbers = √  ab = 20 squaring both sides ab = 400 So now – (a + b)2 = (a- b)2 + 4ab (50)2 – 4 ×400 = (a-b)2 (a-b)2 =2500- 1600 = 900  a – b = 30.
