S1: Production of coins starts with the buying of unmixed metals and their testing by the Assay Department. P: These ingots are reheated until the temperature is hot enough for hot rolling. Q: During this stage, the ingots pass through a series of rollers until they form long, thin sheets which are the thickness of a coin. R: From these thin strips, blank discs are punched. S: Then the metals are alloyed in oil – fired or electric arc furnaces, and cast into ingots 40 cm wide, 15 cm thick and 6 m long. S6: The blanks are heated to soften them, then rolled so that the rim is raised and are stamped with the design of the coin. The Proper sequence should be: A. PRSQ B. PSQR C. SPQR D. SQRP

[amp_mcq option1=”PRSQ” option2=”PSQR” option3=”SPQR” option4=”SQRP” correct=”option1″]

The correct answer is: A. PRSQ

Here is a brief explanation of each option:

• Option A: PRSQ
  This is the correct sequence of events. The first step is to buy unmixed metals and test them. The next step is to alloy the metals and cast them into ingots. The third step is to reheat the ingots and hot roll them into thin sheets. The fourth step is to punch blank discs from the thin sheets. The fifth step is to heat the blanks and roll them so that the rim is raised. The sixth and final step is to stamp the design of the coin on the blanks.

• Option B: PSQR
  This option is incorrect because it has the steps “reheating the ingots” and “hot rolling them into thin sheets” in the wrong order. The ingots should be hot rolled before they are reheated.

• Option C: SPQR
  This option is incorrect because it has the steps “punching blank discs from the thin sheets” and “heating the blanks” in the wrong order. The blanks should be heated before they are punched.

• Option D: SQRP
  This option is incorrect because it has the steps “stamping the design of the coin on the blanks” and “rolling the blanks so that the rim is raised” in the wrong order. The blanks should be rolled so that the rim is raised before they are stamped.
