- Question
How much does a gallon of water weigh?
Options- A. 2.741 kgs
- B. 2.956 kgs
- C. 3.418 kgs
- D. 3.785 kgs
- Correct Answer
- 3.785 kgs
Explanation1 Gallon = 3.785 kgs
Gallon is a unit of measurement of liquid.
We know that 1 gallon = 3.785 liters
But we know that,
1 cubic meter = 1000 lit or 1000 kgs
=> 1 lit = 1 kg
Hence, 1 gallon = 3.785 lit = 3.785 kgs.

Correct Answer: 19
Correct Answer: All of the above
Explanation:
Aptitude tests measures an individual's level of competency to perform a certain type of task and their mental and physical potentials in dealing different situations. These tests include General reasoning, Verbal comprehension, Perceptual speed and numerical operations.
Correct Answer: 0
Explanation:
The place value of 0 in 103 is given by the product of digits place in the number and the digit.
Here 0 is in 10's place in 103
=> 0 x 10 = 0.
Hence, The place value of 0 in 103 = 0.
Correct Answer: 8
Explanation:
Suppose there are 9 balls
Let us give name to each ball B1 B2 B3 B4 B5 B6 B7 B8 B9
Now we will divide all the balls into 3 groups.
Group1 - B1 B2 B3
Group2 - B4 B5 B6
Group3 - B7 B8 B9
Step1 - Now weigh any two groups. Let's assume we choose Group1 on left side of the scale and Group2 on the right side.
So now when we weigh these two groups we can get 3 outcomes.
Weighing scale tilts on left - Group1 has a heavy ball.
Weighing scale tilts on right - Group2 has a heavy ball.
Weighing scale remains balanced - Group3 has a heavy ball.
Lets assume we got the outcome as 3. i.e Group 3 has a heavy ball.
Step2 - Now weigh any two balls from Group3. Lets assume we keep B7 on left side of the scale and B8 on right side.
So now when we weigh these two balls we can get 3 outcomes.
Weighing scale tilts on left - B7 is the heavy ball.
Weighing scale tilts on right - B8 is the heavy ball.
Weighing scale remains balanced - B9 is the heavy ball.
The conclusion we get from this Problem is that each time weigh. We element 2/3 of the balls.
As we came to conclusion that Group3 has the heavy ball from Step1, we remove 6 balls from the equation i.e (2/3) of 9.
Simillarly we do the ame thing for the Step2.
Now going with this conclusion. We have 6561 balls.
Step - 1
Divided into 3 groups
Group1 - 2187Balls
Group2 - 2187Balls
Group3 - 2187Balls
Taking the similar steps as we did in the above example, we come to the conclusion that Group1 has the heavy ball.
Step - 2
Divided into 3 groups
Group1 - 729Balls
Group2 - 729Balls
Group3 - 729Balls
Taking the similar steps as we did in the above example, we come to the conclusion that Group1 has the heavy ball.
Step - 3
Divided into 3 groups
Group1 - 243Balls
Group2 - 243Balls
Group3 - 243Balls
Taking the similar steps as we did in the above example, we come to the conclusion that Group1 has the heavy ball.
Step - 4
Divided into 3 groups
Group1 - 81Balls
Group2 - 81Balls
Group3 - 81Balls
Taking the similar steps as we did in the above example, we come to the conclusion that Group1 has the heavy ball.
Step - 5
Divided into 3 groups
Group1 - 27Balls
Group2 - 27Balls
Group3 - 27Balls
Taking the similar steps as we did in the above example, we come to the conclusion that Group1 has the heavy ball.
Step - 6
Divided into 3 groups
Group1 - 9Balls
Group2 - 9Balls
Group3 - 9Balls
Taking the similar steps as we did in the above example, we come to the conclusion that Group1 has the heavy ball.
Step - 7
Divided into 3 groups
Group1 - 3Balls
Group2 - 3Balls
Group3 - 3Balls
Taking the similar steps as we did in the above example, we come to the conclusion that Group1 has the heavy ball.
Step - 8
So now when we weigh 2 balls out of 3 we can get 3 outcomes.
Weighing scale tilts on left - left side placed is the heavy ball.
Weighing scale tilts on right - right side placed is the heavy ball.
Weighing scale remains balanced - remaining ball is the heavy ball.
So the general answer to this question is, it is always multiple of 3 steps.
For 9 balls = 9. therefore 2 steps
For 6561 balls = 6561 therefore 8 steps
Correct Answer: 3
Correct Answer: 3, 3, 8
Explanation:
Let?s break it down. The product of their ages is 72. So what are the possible choices?
2, 2, 18 ? sum(2, 2, 18) = 22
2, 4, 9 ? sum(2, 4, 9) = 15
2, 6, 6 ? sum(2, 6, 6) = 14
2, 3, 12 ? sum(2, 3, 12) = 17
3, 4, 6 ? sum(3, 4, 6) = 13
3, 3, 8 ? sum(3, 3, 8 ) = 14
1, 8, 9 ? sum(1,8,9) = 18
1, 3, 24 ? sum(1, 3, 24) = 28
1, 4, 18 ? sum(1, 4, 18) = 23
1, 2, 36 ? sum(1, 2, 36) = 39
1, 6, 12 ? sum(1, 6, 12) = 19
The sum of their ages is the same as your birth date. That could be anything from 1 to 31 but the fact that Jack was unable to find out the ages, it means there are two or more combinations with the same sum. From the choices above, only two of them are possible now.
2, 6, 6 ? sum(2, 6, 6) = 14
3, 3, 8 ? sum(3, 3, 8 ) = 14
Since the eldest kid is taking piano lessons, we can eliminate combination 1 since there are two eldest ones. The answer is 3, 3 and 8.
Correct Answer: 12 & 7
Explanation:
x ? y = 5
4x ? 6y = 6
x = 12 y = 7
Correct Answer: 1 hundred, 7 tens, 0 ones
