What is the smallest number of ducks that could swim in this formation - two ducks in front of a duck, two ducks behind a duck and a duck between two ducks ?

Correct Answer: 3.785 kgs

Explanation:

1 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.

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: 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.
