Seven surgeons, W, X, Y, Z, A, B and C, were sitting around a square table, facing the centre. Four of them are sitting at the corners while three are sitting at the exact centre of the sides. One of the centres of the sides was empty. C, at one of the corners, was immediately next to both B and Y. Z was immediately next to both B and X. A was at the immediate right of X.
Which surgeon was third to the right of W?
Simplify 3(3x − 2) + x(\( \frac{4^x}{2} \)) + 15 − 12.
51 men can complete a work in 12 days. Four days after they started working, 6 more men joined them. How many days will they now take to complete the remaining work?
8 \( \frac{1}{19} \) days
5 \( \frac{9}{19} \) days
7 \( \frac{3}{19} \) days
6 \( \frac{7}{19} \) days
