Because arteries need to carry pressurised blood from the heart all throughout the body it has to be pressurized to stop back flow of blood into the heart veins carry deoxygenated blood which is not pressurised so it can be thin hence arteries carry pressurised blood so it is thick so that it does not explode.

300 men can construct a200m long wall in 12 days working 8 hours a day. In how many days can 120 men construct 180 m long wall working 9 hours per day

\(\frac{M_1D_1H_1}{W_1}=\frac{M_2D_2H_2}{W_2}\)  M1 = 300, D1 = 12, H1 = 8, W1 = 200 M2 = 120, D2 = ? H2 = 9, W2 = 180 \(\frac{300\times12\times8}{200}=\frac{120\times D\times7}{180}\) D = 24 days
