    Clearly, we have :B-3 = E ...(i)B + 3 = D ...(ii)A+B = D + E+10 ...(iii)B = C + 2 ...(iv)A+B + C + D + E= 133 ...(v)From (i) and (ii), we have : 2 B = D + E ...(vi)From (iii) and (vi), we have : A = B + 10 ...(vii)Using (iv), (vi) and (vii) in (v), we get:(B + 10) + B + (B - 2) + 2B = 133 5B = 125 B = 25.

MCQ->The simplest method of welding two pieces of metal together is known as pressure welding.The ends of a metal are heated to a white heat-for iron,the welding temperature should be about 1300C-in a flame.At this temperature the metal becomes plastic.The ends are pressed or hammered together,and the joint is smoothed off.Care must be taken to ensure that surfaces are thoroughly clean first,for dirt will weaken the weld.Moreover,the heating of iron or steel to a high temperature cause oxidation,and a film of oxide is added to the heated surfaces.For this reason,flux is applied to the heated metal.At welding heat,flux melts and the oxide particles are dissolved in it together with any other impurities which may be present.The metal surfaces are pressed together,and the flux is squeezed out from the center of the weld.A number of different types of weld may be used,but for fairly thick bars of metals,a vee-shaped belt should be normally employed.It is rather stronger than ordinary butt weld. The simplest way of welding two pieces of metal together is....
