Who among the following may have an experience of ten years ?

A is more experienced than two employees, => A is the 4th most experienced employee. 

D has more experience than employee C and D has less experience than employee F, => F > D > C. 

E has less experience than D and E does not have the least experience. Also, F is not the most experienced employee

=> B is the most experienced employee and C is the least experienced.

Combining above statements, we get :

$$\therefore$$ B > F > D > A > E > C

Experience of F = 13 years and E = 5 years

Since, A and D lies between F and E. Thus, either A or D may have an experience of 10 years.

=> Ans - (D)
