For a number to be divisible by 11, we add the numbers at odd places and even places and subtract the sums. If the answer is 0 or divisible by 11, then the number is divisible by 11.
1595:(5+5)−(9+1)=0
1629:(9+6)−(2+1)=15−3=12
1785:(5+7)−(8+1)=12−9=3
∴ In the given options, only 1595 is matching the rules of divisiblility for 11.
