the sum of the digits of the two digit number is 15.the number obtained by interchanging its digits exceeds the given number by 9. find the original number.
Find the values of A, B, C, D,E,F, G, H, and I if ABC + DEF = GHI when A x B = 3
If 24x is a multiple of 3, where x is a digit, what is the value of x?
(Since 24x is a multiple of 3, its sum of digits 6 + x is a multiple of 3; so 6 + x is one of these numbers: 0, 3, 6, 9, 12, 15, 18…. But since x is a digit, it can only be that 6 + x = 6 or 9 or 12 or 15. Therefore, x = 0 or 3 or 6 or 9. Thus, x can have any of four different values)
A] find all possible values of x for which the number 7x3 is divisible by 3 . also find each such number.
B] find all possible values of y for which the number 53y1 is divisible by3 .also find each such number.
-20 = -20
16-36= 25-45
16-36 +(9/2)= 25-45 +(9/2) (adding 9/2 on both sides)
(4-9/2) (4-9/2)= (5-9/2) (5-9/2) (by a-b whole square formula)
4=5 (-9/2 = -9/2 )
where 4 is not = 5 find out mistake
