The sum of the present ages of Alok and Prakash is 60 years. Six years ago, Alok's age was five times the age of Prakash. What will be the age of Prakash after 6 years ?

1)	16 years	2)	18 years
3)	20 years	4)	24 years
5)	None of these

Answer : 20 years
Explanation :

Let, the present ages of Alok and Prakash be x and (60 -x) years respectively.

Then, (60 - x) - 6 = 5(x - 6)

54 - x = 5x - 30

or 6x = 84

or x = 14.

So, Prakash's age after 6 years = (x+ 6) = 20 years.

B's age 5 years back (24 - 5) = 19 years.

The sum of two numbers is 27 and their H.C.F is 3. If one of the number is lies between 13 to 16, the find the value of the other number ?

1)	12	2)	15
3)	18	4)	24
5)	None of these

Answer : 12
Explanation : Let, two numbers are 3x and 3y respectively.

Then, 3x + 3y = 27

or 3 (x + y) = 27

or (x + y) = 27/3 = 9

So, pairs of numbers are 9 = (1,8) , (2,7) , ( 3,6) and (4,5) .

Thus the numbers are 3 x 4 = 12 and 3 x 5 =15
