Direction (1 - 5): Study the following data carefully and answer the questions:

Read the data given in the paragraph carefully and answer the following questions:

In a factory, labour productivity is calculated on yearly basis. There are total two types of productivity: Labour productivity per hour and Labour productivity per worker. Formula to calculate labour productivity is given below:

Labour productivity per hour = Worth of Output produced/Total hours input

Labour productivity per worker = Worth of Output produced/Total workers input

Also, there is one more term called efficiency to calculate the efficiency of the workforce of the company. Formula to calculate efficiency is given below:

Efficiency = (Standard Labour Hours/Amount of Time Worked) * 100

Table given below shows the Standard Labour hours and total number of workers allotted for the work on five different years in the company:

1) If in 2011, efficiency of the workforce of the company is 66(2/3)% and Labour productivity per hour is Rs.105/hour, then what is the total worth of the output produced by the company in 2011?

A.Rs.12600

B.Rs.13200

C.Rs.11400

D.Rs.10800

E.None of these

2) If labour productivity per worker and efficiency of the company in 2012 is Rs.175/worker and 120% respectively, then what is the labour productivity per hour of the company in 2012?

A.Rs.190 per hour

B. Rs.225 per hour

C. Rs.185 per hour

D. Rs.210 per hour

E.None of these

3) If labour productivity per hour and labour productivity per worker of the company in 2013 is Rs.90/hour and Rs.180/worker, then what is the efficiency of company in 2013?

A.80%

B.125%

C.120%

D.75%

E.None of these

4) If efficiency of the company in 2014 is 125% and labour productivity per hour of the company in 2014 is Rs.75/hour, then what is the labour productivity per worker (of the company) in 2014?

A.Rs.125.5

B.Rs.112.5

C.Rs.87.5

D.Rs.145.5

E.None of these

5) If efficiency of the company in 2015 is 62.5% and total worth of output produced by the company in 2015 is Rs.18600, then what is the difference between labour productivity per hour and labour productivity per worker of the company in 2015?

A.Rs.205

B.Rs.125

C.Rs.155

D.Rs.145

E.None of these

Answers :

1) Answer: A

Efficiency = (80/Amount of time worked) * 100

66(2/3) = (80/Amount of time worked) * 100

Amount of time worked = 120 hours

Labour productivity per hour = Worth of Output produced/Total hours input

105 = Worth of Output produced/120

Worth of Output produced = 105 * 120 = Rs.12600

2) Answer: D

Labour productivity per worker = Worth of Output produced/Total workers input

175 = Worth of output produced/60

Worth of output produced = 175 * 60 = Rs.10500

Efficiency = (Standard Labour Hours/Amount of Time Worked) * 100

120 = (60/Amount of time worked) * 100

6/5 = (60/Amount of time worked) * 100

Amount of time worked = 50 hours

Labour productivity per hour = Worth of Output produced/Total hours input

= 10500/50

 = Rs.210 per hour

3) Answer: C

Labour productivity per worker = Worth of Output produced/Total workers input

180 = Worth of Output produced/50

Worth of Output produced = 180 * 50 = Rs.9000

Labour productivity per hour = Worth of Output produced/Total hours input

90 = 9000/Total hours input

Total hours input = 9000/90 = 100 hours

Required efficiency = (120/100) * 100 = 120%

4) Answer: B

Efficiency = (Standard Labour Hours/Amount of Time Worked) * 100

125 = (150/Amount of Time Worked) * 100

Amount of Time Worked = (150 * 100)/125 = 120 hours

Labour productivity per hour = Worth of Output produced/Total hours input

75 = Worth of Output produced/120

Worth of Output produced = 75 * 120 = Rs.9000

Labour productivity per worker = Worth of Output produced/Total workers input

= 9000/80

= Rs.112.5 per worker

5) Answer: C

Efficiency = (Standard Labour Hours/Amount of Time Worked) * 100

62.5 = (125/Amount of Time Worked) * 100

Amount of Time Worked = (125 * 100)/62.5 = 200 hours

Total worth of output produced by the company in 2015 = Rs.18600

Labour productivity per hour = Worth of Output produced/Total hours input

= 18600/200 = Rs.93/hour

Labour productivity per worker = Worth of Output produced/Total workers input

= 18600/75 = Rs.248/worker

Required difference = 248 – 93 = Rs.155
