Ones upon a time one old man was living with three sons. Old man had 19 Cows. One day he fell ill and after his death , his son read the will. 1) My eldest son will get 1/2 of my cows 2) My second son will get 1/4 of my cows 3) my youngest son will get 1/5 of my cows Can you distribute the cows as per will. How many cows each of them got ? ===================================================================== Question : For any 9 digit number not ending in Zero. Prove that sum of this number with the number formed by writing its digits in reverse order will always contain at least one even digit ? Hint  :  middle digit of sum (S5) is twice of the middle digit of said number so S5 will be even . Now to make the S5 to odd we need carry from the S4. In this case S6 will also generate the carry if S3 is odd the carry of S6 will make the S7 to even number. =========================================== Question : Answer 1000 /- ===============================

Question : There are three numbers such that the product of the first two numbers is 91                  and that of the last two numbers is 221. Find all three numbes and their sum Answer : Suppose numbers are A , B AND C. Also given   A x B  = 91 and B x C = 221 Since the numbers are prime number, they contain only 1 as the common factor. Also, above two products have B in common. So, B = H.C.F. of ( 91 and 221 ) = 13; A  = 91/13 = 7;  C  = 221/13 = 17. Required sum = (7 + 13 + 21 ) = 41. ================================================================= Question : The ratio of two numbers is 3 : 4. The L.C.M. of two numbers is 48.                   Find sum of the number Solution : Let the numbers be 3x and 4x. Then, their L.C.M. = 12x. So, 12x = 48 or x = 4 The numbers are 12 and 16. Hence, required sum = (12 + 16) = 28. ================================================================ Important points regarding LCM and HCF m

Factor :   Factor for a given number are all the numbers which divides given number completely i.e. if you divide given number by factor then there will be no remainder. Question Write all the factors of 100 ? Prime Number : are the numbers which divided completely by only itself or one.               example 2 , 3 , 5 so on Question :   Write all the prime number till 100 ? ========================================================= HCF : Highest common factor of two or more number is the largest number that divide all the number completely    Factor of 10 are 1 ,  2  and 5    Factor of 15 are 1 , 3   and 5  so common factor of 10 and 15 are 1 and 5 in  which 5 is largest so HCF = 5 Note : HCF will be always less than the smallest number or equal to the smallest number.            HCF for prime numbers is 1. i.e there is no common factor other than 1. ========================================================== LCM : Least common multiple is the smallest non zero

Question 1): The difference of the squares of two consecutive even integers is divisible by which of the following numbers? Option :  A) 3      B) 4       C) 5        D) 6 Solution  1) Let two consecutive  even integers are A and A+2  then difference of their squares will be   (A + 2)2  - (A)2   =  4A + 4 = 4 ( A + 1) So it will be divisible by 4. =========================================== Question : Find out the smallest value of # in number 1425#8 if number is completely divisible by 3 Option : A) 0      B) 1      C) 2       D) 3 Answer :  B) 1  Note : A number is divisible by 3 if the sum of the digits is divisible by 3. ================================================= Question :  Find out the largest value of # in number   461#12  if number is completely divisible by 4 option :  A)  5      b)   8        C) 9      D) 4 Answer C) 9 Note :  If the last two digits of a whole number are divisible by 4, then the entire number is divisible by 4
