**Direction: **Answer the questions based on the following table.

Machine M1 as well as machine M2 can independently produce either product P or product Q. The time taken by machines M1 and M2 (in minutes) to produce one unit of product P and product Q are given in the table below: (Each machine works 8 hour per day).

**31. CAT 1995 LRDI | DI - Tables & Graphs**

What is the maximum number of units that can be manufactured in one day?

- A.
140

- B.
160

- C.
120

- D.
180

Answer: Option B

**Explanation** :

Since time taken to manufacture Q by both the machines is the least, we have to manufacture only Q in order to maximize the output for the day. In such a case, total number of units of Q produced by M1 = $\frac{(8\times 60)}{6}$ = 80 units and that by M2 = $\frac{(8\times 60)}{6}$ = 60 units. So the maximum number of units that can be produced in one day = (80 + 80) = 160 units.

Workspace:

**32. CAT 1995 LRDI | DI - Tables & Graphs**

If M1 works at half its normal efficiency, what is the maximum number of units produced, if at least one unit of each must be produced?

- A.
96

- B.
89

- C.
100

- D.
119

Answer: Option D

**Explanation** :

If M1 works at half of its normal efficiency, time taken by M1 to manufacture 1 unit of P = 20 min and Q = 12 min. For producing maximum number of units, we have to produce Q on M2 first as it takes only 6 min per piece.

Also since at least one unit of P has to be manufactured and it is more efficient to do so on M2, we would do that. So time taken to manufacture 1 unit of P on M2 = 8 min.

Hence, time remaining on M2 = (480 – 8) = 472. In this remaining time number of units of Q that can be manufactured on M2 = $\frac{472}{6}$ = 78 (only completed units taken). Now since it takes less time to manufacture Q on M1 as well, we will maximize Q on M1. Since 1 unit of number of units that can be produced = $\frac{(8\times 60)}{12}$ = 40.

Hence, the total number of units manufactured = (1 + 78 + 40) = 119 units.

Workspace:

**33. CAT 1995 LRDI | DI - Tables & Graphs**

What is the least number of machine hours required to produce 30 pieces of P and 25 pieces of Q respectively?

- A.
6 hr 30 min

- B.
7 hr 24 min

- C.
6 hr 48 min

- D.
4 hr 6 min

Answer: Option A

**Explanation** :

In order to minimize time required, we will manufacture P on M2 and Q on M1. Number of machine hours required to manufacture 30 units of P on M2 = (30 × 8) = 240 min = 4 hr. Number of machine hours required to manufacture 25 units of Q on M1 = (25 × 6) = 150 min = 2.5 hr. So total time taken = (4 + 2.5) = 6.5 hr or 6 hr 30 min.

Workspace:

**34. CAT 1995 LRDI | DI - Tables & Graphs**

If the number of units of P is to be three times that of Q, what is the maximum idle time to maximize total units manufactured?

- A.
0 min

- B.
24 min

- C.
1 hr

- D.
2 hr

Answer: Option A

**Explanation** :

Since P has to be produced in more number than Q and since time taken to produce P is least on M2, to maximize the output utilize the entire time available on M2 for producing P. Number of units of P produced in this time $=\frac{(8\times 60)}{8}$ = 60 units. Now since the number of units of Q should be one-third that of P, we should manufacture 20 units of Q. To manufacture this on M1, it would take (20 × 6) = 120 min. So there are still (480 – 120) = 360 min of M1 to be utilized. Now for every 3 units of P that is manufactured, we have to manufacture 1 unit of Q. To run one such cycle on M1, it would take (3 × 10 + 1 × 6) = 36 min. Hence in 360 min, we have 10 such cycles and utilize all the idle time of M1. Hence, to maximize the output under the given condition it is possible to have no idle time on any of the machines.

If equal quantities of both are to be produced, then out of the four choices given below, the least efficient way would be

- A.
48 of each with 3 min idle

- B.
64 of each with 12 min idle

- C.
53 of each with 10 min idle

- D.
71 of each with 9 min idle

Answer: Option C

**Explanation** :

The least efficient way is the option that gives least production with highest idle time. So we can compare

the options in the following two ways. Assume that production is constant (viz. LCM of 48, 64, 53 and 71) in all 4 options and compare the corresponding idle time. Or we can assume the idle time to be constant (viz. LCM of 3, 12, 10 and 9) in all 4 options and compare the corresponding production. The latter method is more preferable as finding LCM of idle time is easier. So LCM of 3, 12, 10, 9 = 180. If we assume that the idle time has to be 180 min, then as per option (a) we would get production $=\left(\frac{180}{3}\times 48\right)$ = 2,880 units, as per option (b), we would get production $=\left(\frac{180}{12}\times 64\right)$ = 960 units, as per option (c), production = $\left(\frac{180}{10}\times 53\right)$ = 954 units and as per option (d), production = $\left(\frac{180}{9}\times 71\right)$ = 1,420 units. Since option (c) gives the least production, it is the least efficient way.
