Correct Answer: C
Solution :
(P) Since, \[213\times 27\] is divisible by 9. So, 2+1+3+x+2+7=15+xis divisible by 9. \[\therefore \] x=3 (Q) \[2415x\] is divisible by 6, if it is divisible by both 2 and 3. \[\therefore x=6\] (R) \[23245x\] is divisible by 4 and 3 \[\Rightarrow 5x\] is divisible by 4 \[\therefore \] Possible values of x are 2, 6 Also, \[2+3+2+4+5+x=16+x\] is divisible by 3. \[\therefore \] Possible values of \[x\] is 2. (S) We have, \[7251x\text{ }93\] is divisible by 11 \[\therefore [(7\text{ }+\text{ }5\text{ }+\text{ }x\text{ }+\text{ }3)\text{ }-\text{ }(2\text{ }+\text{ }1\text{ }+\text{ }9)]\] is divisible by 11 \[\Rightarrow 15+x-12=3+x\] is divisible by 11 \[\therefore x\] can be equal to 8.
