One day on reaching school I found there were a total of 16 bicycles and tricycles parked in the school compound. I counted the total number of wheels to be 38. Find out the number of bicycles.

10 bicycles.

**Explanation:**: All the cycles will have at least 2 wheels, so 16 cycles will have 16x2=32 wheels. But in total there are 38 wheels. So the extra wheels (38-32=6) must be of the tricycles because bicycles have 2 wheels and tricycles have 3 wheels.

Therefore, the number of tricycles parked is 6 and hence the number of bicycles is 10.

If the sum he paid whilst purchasing 20 pens = A,

Then the Cost Price of each pen = A/20.

Since the amount he got whilst selling 15 pens is also = A

Then the Selling Price of each pen = A/15.

Since Selling Price > Cost Price, he made a profit.

Profit per pen = Selling Price - Cost Price = A/15 - A/20 = A/60.

Profit percentage per pen = Profit per pen / Cost per pen x 100 = (A/60) / (A/20) x 100 = 33.33%

A friend in need is a friend indeed.

Explanation: Write the alphabets in four rows for example:

12223251819.

Explanation: First letter is written as its position in alphabetical order, the second letter is written as its position plus 2, third letter is written as its position plus 3 and so on.

VEHICLE

Explanation: Each letter in the old word is the same number of places from the start of the alphabet as its corresponding letter in the new word is from the end of the alphabet. For e.g. Look at the below two words:

**C**AB

**X**ZY

"C" is 3rd in the alphabetic (from the start), and its corresponding letter in the new word, "X", is 3rd in the alphabet (from the end). Similarly, let's look at the third letter in the same two words:

CA**B**

XZ**Y**

"B" is 2nd in the alphabet and so is its corresponding letter, "Y", from the end of the alphabet. If we use the same logic, then "EVSRXOV" will give us "VEHICLE".

Remove "s" from seven.

7917510

**Explanation**:

All letters whose position in the alphabet is below 10, are being represented by their position number.

All letters whose position is 10 or more, are being represented by their position number minus ten.

Therefore:

G is 7

R is 18-9=9

A is 1

P is 16-9=7

E is 5

S is 19-9=10

Take "I" away from Roman 19 (XIX) and you will get Roman 20 (XX).
