Problems On Number

Your Answer

4 would be the right answer. Here because we can see - 10*9=90 Hence the no should also be divided by 10 and according to divisiblity rule of 10 the no conatains 0 at one's place is divisible by it. So in the given question 653XY, Y must be 0. According to divisiblity rule of 9, the sum of digits should be divisible by 9. Hence 653X having sum of digits as 14+X, which is near to 18 because 18 is divisible by 9. So value of X+Y=4+0=4
