Math puzzle 4:
The product of two numbers is 1575 and their quotient is 9/7. Then the sum of the numbers is?
Reply:
Suppose the numbers are x and y.
We know xy = 1575
And x/y = 9/7
We know xy/x/y = 1575/9/7
We know y2 = 1225
We know y = 35 and x = 45
We know Sum of numbers = 45+35
= 80
Math puzzle 5:
The sum of squares of two consecutive odd numbers is 394. The sum of those numbers is?
Reply:
Suppose the consecutive odd numbers are x and (x+2)
We know that x2 + (x + 2)2 = 394
We know x2 + x2 + 4x + 4 = 394
We know 2 x2 +4x – 390 = 0
We know x2 + 2x – 195 = 0
We know (x +15) (x-13) = 0
We know x = 13
We know Required Total = 13 +15 =28
