Q:
The sum of the squares of two natural consecutive odd numbers is 394. The sum of the numbers is –
755 0

Answer : 4. "28"
Explanation :
Let the consecutive odd numbers be 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 sum = 13 +15 =28

Q:
The value of (81)3.6 * (9)2.7/ (81)4.2 * (3) is __
1021 0

Answer : 3. "9"
Explanation :
(81)3.6 * (9)2.7/(81)4.2 * (3) = (3)14.4 * (3)5.4/(3)16.8 * (3)
= 314.4+5.4-16.8-1
= 32
= 9

Q:
The product of 2 numbers is 1575 and their quotient is 9/7. Then the sum of the numbers is –
736 0

Answer : 3. "80"
Explanation :
Let the numbers be 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 The sum of the numbers = 45+35
= 80
