Question
If x and y are two digits of the number 85254xy such
that this number is divisible by 90. Find the minimum value of x + y?Solution
90 can be written as 10×9 So, we have here number 85254xy For 10 we know that last digit should be zero. So, we have y is zero. For 9 we know that sum of digit should be divisible by 9 8+5+2+5+4+x+y=24+x+y And we have y is zero So, x can be only 3 because we are considering a digit So, x+y=3+0=3 ans. option 2 is right.
