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. ===...
