In the question below, are given a statement followed by three courses of actions numbered I, II and III. On the basis of the information given, you have to assume everything in the statement to be true, and then decide which of the following suggested courses of actions logically follow(s) for pursuing. Statement: Specialty steel and wire ropes maker Usha Martin's decision to sell one of its core businesses - steelmaking - to prune outstanding debt, marks the rare instance of an Indian corporate borrower meeting its loan obligations through divestment. The slump sale is a milestone in the six-decade history of the Kolkata-based company, whose board on Saturday approved the divestment of its one million ton steel business in favor of Tata Steel for Rs 4,600 crore.  Courses of action: I. Proceeds will be used to ‘first repay existing lenders of the company’. Usha Martin will retain a profitable wire ropes unit as residual business, and has plans to scale it up significantly.  II. As part of the transaction, Usha Martin has entered into a five-year deal with The Tatas for sale of steel at market price to the wire-ropes business.  III. Usha Martin is among the top four wire rope players globally. With oil prices going up and strong trend in demand in Europe, the Ebitda in the wire-ropes business has improved.

500 kg of ore contained a certain amount of steel. After the first blast furnace process, 200 kg of slag containing 12.5% of steel was removed. The percentage of steel in the remaining ore was found to be 20% more than the percentage in the original ore. How many kg of steel were there in the original 500 kg ore?
Two similar bars of Steel and Aluminium are heated to a same temperature. Forces are applied at the ends of the bars to maintain their lengths unaltered. If the ratio of Young’s moduli of Steel and Aluminium is 3, and the ratio of the coefficients of thermal expansion of Steel to that of Aluminium is 0.5, what is the stress on the Aluminium bar if the stress on the Steel bar is 100 MPa?
A steel ball (density ρsteel = 7200 kg/m3) is placed in an upward moving liquid AI (density ρal = 2360 kg/m3, viscosity μAl = 1 × 10-3 Pa.s and Reynolds number = 5 × 105). The force (F) exerted on the steel ball is expressed as F = fπR2(ρAl V2/2)
where, f is friction factor (= 0.2), v is the velocity of liquid AI and R is the radius of steel ball.
The force exerted on the steel ball is
