Following are few examples of solved problems.

If the letters of the word " FATHER" are arranged alphabetically as in a dictionary, show that it will occur as the 261 word.

There are six letters in the word "FATHER". Since the words are arranged alphabetically, first comes the words starting with A. Then starting with E and then comes the words starting with F. To find the number of words beginning with A, keep A fixed at the first letter and arrange the remaining 5 letters. This can be done in 5! = 120 ways. Similarly the number of words starting with E is 120. Therefore the total number of words beginning with A and E is 240. Now the words begin with F. To find the words beginning with FA, arrange the remaining 4 letters which can be done in 4! = 24 ways. The 241th word is" FAEHRT" and 240+24 = 264 th word is "FATRHE". THE 263RD WORD IS :fatreh" and the 262nd word is "FATHRE".

If the roots of the equation x

Since α and β are the roots of the equation x

Now sum of the roots α

=(α + β)

= 2

= 4 -14 + 2 = -8

Product of the roots = (α

= α

= 7

= 49 + 8 - 42 + 7

= 22

Therefore the equation whose roots are α

x

That is

Example 3: -

Let the numbers be a - d, a, a + d

Given that the sum of the number is 42.

That is a - d + a + a + d = 42

3a = 42

That is a = 42/3 =14.

Also given product of the numbers is 2618

That is (a - d) a(a + d) = 2618

a(a

14(14

Dividing both sides by 14, we get

14

subtracting 142 from both sides, we get

-d

That is d = ± 3

When d = -3 and a = 14, the numbers are 17, 14, 11.
