19. If the number 345xy is divisible by 90, then (x + y)?
- Option : D
- Explanation : Any number, that is divisible by 90, must be A
divisible by 9 and 10.
Now, for divisibility by 10, last digit of that number must be '0'. And for divisibility by 9 sum of digits of that number must be divisible by 9.
Here given number is 345xy
To divisible by 10, y = 0
To divisible by 9, (3 + 4 + 5 + x + 0) must be a multiple of 9.
12 + x = 9 x 2
x = 18-12 = 6
Hence,x+y = 6 + 0 = 6.
- Option : B
- Explanation : 1n the process of deduction, the premises are assumed to be true to determine! prove/ conclude what would logically follow or will have to be true if the premises are true. The premises are intended to provide such strong support for the conclusion that, if the premises are true, then it would be impossible for the conclusion to be false.
