Q:

# If you write down all the numbers from 1 to 100, then how many times do you write 3 ?

 A) 11 B) 18 C) 20 D) 21

Explanation:

Clearly, From 1 to 100, there are ten numbers with 3 as the unit's digit - 3, 13, 23, 33, 43, 53, 63, 73, 83, 93 and ten numbers with 3 as the ten's digit - 30, 31, 32, 33, 34, 35, 36, 37, 38, 39.

So, required number = 10 + 10 = 20.

Q:

How much does a gallon of water weigh?

 A) 2.741 kgs B) 2.956 kgs C) 3.418 kgs D) 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.

Q:

0 divided by 0

 A) 0 B) 1 C) Undefined D) Indeterminate

Explanation:

Indeterminate are those,which mathematics can’t determine.

Because we don’t actually know which one is the exact answer for this due to having lots of results for this.

Explanation::

• Let us think by this analogy that,

0 / 1 = 0

0 / 2 = 0

…………

………..

we can say 0 / n = 0 from this we can write, 0/0 = 0

• Again, another analogy,(from limiting concept of 1/0 = infinity)

1 / 0 = + or -

2 /0 = + or -

………

.…….

we can say 0 / 0 =

• Again, another analogy,

1 / 1 = 1

2/2 = 1

.……..

………..

we can say, 0/0 = 1

Now, you see it’s confusing. Every analog is mathematically correct then which one is the right answer for 0/0.  Therefore Mathematics can’t determine this fact.

So, 0/0 is indeterminate.

Q:

How Many Hours Is 100 Miles?

It depends on the speed with what you are travelling.

• For example, if you have travelled 100 miles and it took 2.5 hours to do it, then that is 100 miles = 2.5 hrs for you.

And the Average Speed is given by 100/2.5 = 40 miles per 1hour.

Q:

What are the Multiples of 18?

 A) 144 B) 72 C) 306 D) All the above

Explanation:

The Multiples of 18 are 18, 36, 54, 72, 90, 108, 126, ....

• Multiples of 18 are nothing but numbers which are divisible by 18 leaving remainder 0.

• An infinite number of multiples of 18 can be achieved by adding 18 to each subsequent multiple.

Q:

7 is to 34 as 5 is to

 A) 33 B) 24 C) 54 D) 41

Explanation:

We can get this by any of two explanations.

7 = 3 + 4  = 34

Similarly, 5 = 4 + 1  = 41

7 - 3 = 4  => 34

Similarly, 5 - 4 = 1  => 41
