A) \[60\]
B) \[92\]
C) \[52\]
D) \[48\]
Correct Answer: C
Solution :
The three digit number is termed, if unit place is either 0, 2 or 4. Case I when 0 is in unit place, then number of ways \[{{=}^{5=20}}{{P}_{2}}\] Case II When 2 or 4 in unit place, then number of ways \[{{=}^{5}}{{p}_{2}}{{\times }^{2}}{{C}_{1}}=40\] Now, we have to subtract those case in which 0 is in hundred place. If 0 is in hundred place and 2 or 4 in unit place, then number of ways \[{{=}^{4}}{{C}_{1}}{{\times }^{2}}{{C}_{1}}=8\] \[\therefore \] Required number of ways \[=20+40-8=52\]You need to login to perform this action.
