Let letter h stand for a nonzero digit. the three digit number hhh is always divisible

If the sum of the digits is a multiple of three so is the original number (this is because 10 and 1 have the same remainder when divided by 3).

We know H+H+H is divisible by three (zero or not) so so is HHH.

3

option 1 is correct.

step-by-step explanation:

y varies inversely with x and constant of variation is 4

the equation will be:

y = k/x

where k =4 so,

y = 4/x

if we put values of x of option 1 in the above equation and find values of y

y = 4/-2 => y =-2

y = 4/-1 => y = -4

y = 4/1 => y = 4

y = 4/2 => y =2

so, all the values of x and y are correct.

if we put values of x given in other options and find value of y we cannot find whole table satisfying the equation.

hence option 1 is correct.
