puys solve this question..
which book out of these two is better for quant?
Trial and error method...
It's evident that the number is between 100-198. It should be divisible by 6.
so start with 126. (say)
Reverse digits of (1/6 of 126) = 10 + 2/6 of 126 ----- NO
then .. 138 ... 156 etc...
It will match in case of 156.
1/6 of 156 = 26... Reverse is = 62. 62=10+2/6 of 156..
So the answer is 1+5+6 = 12..
