Arithmetic mean of two numbers whose sum is equal to 28, is equal to the geometrical mean of two perfect square numbers. Sum of these perfect square number out of given ten option will be
1) 42 2) 45 3) 48 4) 49 5) 51 6) 52 7) 53 8) 56 9) 58 10)60
28/2 = (49*4)^2------through given condition So sum of 49+4 = 53 So option 7 is correct
