C Either I or II is sufficient

D Neither I nor II is sufficient

E Both I and II are sufficient

ANS:A - I alone is sufficient while II alone is not sufficient

Explanation: From I, we have: number of employees who opted for VRS = 18% of 950 + 6% of 1100 = 171 + 66 = 237. From II, we cannot get the required answer until and unless the number of employees in age-group 51 to 56 and other age-groups is known.
