Question - 1:If the sum of two numbers is 22 and the sum of their squares is 404, then the product of the numbers is?
- 40
- 44
- 80
- 88
Show/Hide Answer
Answer = A - 40
Explanation: Let the numbers be x and y.
Then, (x+y) = 22
and x2+y2 = 404.
Now, 2xy= (x+y)2 - (x2+y2)
= (22)2 - 404
= 484 - 404
= 80
Therefore xy = 40.
Question - 2: If the number 517 * 324 is completely divisible by 3, then the smallest whole number in the place of * will be: ? Explanation: Let the numbers be x and y.
Then, (x+y) = 22
and x2+y2 = 404.
Now, 2xy= (x+y)2 - (x2+y2)
= (22)2 - 404
= 484 - 404
= 80
Therefore xy = 40.

Question - 3:The difference between two numbers is 1356. When the larger number is divided by the smaller one, the quotient is 6 and the remainder is 15. The smaller number is ? Explanation: No Explanation
- 240
- 270
- 295
- 360
Show/Hide Answer
Answer = B - 270
Explanation: Let the numbers be x and (x + 1356).
Then, x + 1356 = 6x+15
‹=› 5x = 1350
x = 270.
Question - 4:Find a positive number which when increased by 17 is equal to 60 times the reciprocal of the number. ? Explanation: Let the numbers be x and (x + 1356).
Then, x + 1356 = 6x+15
‹=› 5x = 1350
x = 270.

Question - 5:The sum of two numbers is 40 and their product is 375. What will be the sum of their reciprocals? ? Explanation: No Explanation
- 1/40
- 8/75
- 75/4
- 75/8
Show/Hide Answer
Answer = B - 8/75
Explanation: Let the numbers be x and y.
Then, x + y = 40 and xy = 375.
Therefore, 1/x + 1/y
‹=› x + y / xy.
‹=› 40/375.
= 8 / 75.
Question - 6:find the number, difference between number and its 3/5 is 50. ? Explanation: Let the numbers be x and y.
Then, x + y = 40 and xy = 375.
Therefore, 1/x + 1/y
‹=› x + y / xy.
‹=› 40/375.
= 8 / 75.
