Answer / v.n.dubey
the 4 digit numbers that will be formed from ( 6,2,7,5)with
no repetition, can not divisible by 36.
because these no. must be divisible by 6.
A no. will be divisible by 6 when it is also divisible by 2
and 3.
so some of these formed no. divisible by 2 ( eg.7562,5726
etc) but not divisible by 3
becase ( 7+5+6+2)=20 { according to divisibility check}
which is not multiple of 3.

The multiples of 36 are 36,72,108,114,180..
the last digits are 6,2,8,4,0

accopied by 6 or 2 in 2c1 ways
The first 3 digits in 3! ways
Therefore the number of possible ways is 3!*2c1=12
