Question

Forces of magnitudes $3, P, 5, 10$ and $Q$ are respectively acting along the sides $A B, B C, C D, A D$ and the diagonal $C A$ of a reactangle $A B C D$ , where $A B = 4$ m and $B C = 3$ m If the resultant is a single force along the other diagonal $B D$ , then $P, Q$ and the resultant are

4, 10 \frac{5}{12}, 12 \frac{11}{12}
