This set has 5 data interpretation questions and their solutions.

DIRECTIONS : Answer the questions on the basis of the information given below.

ABC is a firm which deals with furniture. Manufacturing of table requires three levels of assembly. The finished table is at first level. The leg assembly and table top are second level. The pieces that go into the leg assembly are at the third level which consist of short rails, long rails and legs. One unit of table requires one unit of tabletop and one unit of leg assembly. One unit of leg assembly requires 2 units of short rails, 2 units of long rails and 4 units. Orders are placed just in time to minimise storage.

The lead time for activities are (Lead time is waiting time required to complete one activity)

The availability of part at present time

Demand of finished Tables


1.     For meeting the demand of 200 units of finished table of week 4, when would the first order of tabletops be placed?

        (a) Week 1

        (b) Week 3

        (c) Week 4

        (d) Week 5

   2.   What is the net requirement of legs for meeting the demand of week 4 finished table?

        (a) 200

        (b) 50

        (c) 400

        (d) 800

   3.   When and how many units of shortrail would be placed for meeting the demand of finished table of week 6?

        (a) 100 units in week 1

        (b) 200 units in week 3

        (c) 300 units in week 6

        (d) Data insufficient

   4.   If in-hand units of legs are increased from 150 to 300, then what would be the net requirements of legs for meeting the demand of finished table of week 5?

        (a) 1800, 900

        (b) 2200, 1100

        (c) 1600, 800

        (d) 800, 400

5.     The supplier of long rails has shifted his manufacturing unit to its new location. Because of this the delivery time of long rail has been increased by 1 week. When would the order of long rails be placed to meet the week 5 demand of finished table?

        (a) Week 1

        (b) Week 4

        (c) Week 5

        (d) None of above


Answers and solutions:

  1. a          Week 1, for detailed solution refer the table below.
  2. b          50, for detailed solution refer the table below.
  3. b          200 units’ week 3, for detailed solution refer the table below. The gross requirement of leg is 200 and 600 in week 3 out of 300 in – hand units of legs, 200 units would be used for wek2 requirement and the rest units would be used for meeting the requirements of week 3. Therefore net requirement of week would be 600 – 100 = 500 units of legs for meeting the demand of finished table of week 5. 
  4. b          For meeting the additional demand of 200 tables Shortrails = 4 ×200 = 800. Legs = 8 × 200 = 1600. Total shortrails = 300 + 800 = 1100. Total legs = 600 + 1600= 2200.
  5. a          Details of components available on a particular week.
Figure in bracket represent the week to which components belong.
Details of component ordered on a particular week.
As lead – time increased by 1 week so planned order release would be by one week ahead.
