Multiple choice

Passage

Directions: Answer the question on the basis of the information given below. PQR Forgings manufactures a special alloy called Alloy-X using two metals − Metal-A and Metal-B. For manufacturing Alloy-X, 44% of Metal-A and 27% of Metal-B are required. The manufacturing of Alloy-X happens only in lots of 100 kg and manufacturing of any lot of Alloy-X can begin only if the quantities of metals available are sufficient to manufacture 100 kg of Alloy-X. Further, only when there is a shortfall in any metal, because of which it is not possible to manufacture the subsequent lot of Alloy-X, is that metal extracted from its ore. Given below is a table of PQR Forgings, regarding the number of lots of Alloy-X manufactured on each day and the type and quantity of metals extracted from its ore, if any. The entries in the table on any day were made in the chronological order. Day Quantity of Alloy-X Manufactured (In kg) Quantity of Metal-A Extracted from its Ore (In kg) Quantity of Metal-B Extracted from its Ore (In kg) Day-1 700 - - Day-2 800 - - Day-3 500 500 - Day-4 500 - 400 Day-5 700 600 - Day-6 700 - 300 Day-7 600 800 - Day-8 600 - 400 Day-9 700 - - Day-10 600 300 -

Which of the following could be the total quantity of Metal-A and Metal-B combined after exactly 38 lots were manufactured?

  1. 389 kg

  2. 393 kg

  3. 410 kg

  4. 406 kg
