Comment below your score, considering each question has 1 mark only. If you scored 8 to 10, congratulations! You are one step closer to selection. If you have scored 5 to 8 marks, then you are doing well, keep it up. If you have scored less than 5 marks then you need to work a little harder on this subject. But don&#39;t worry, we are here to help you master the subject.

Let&#39;s check the answers and solutions and try to find out what went wrong. 
 

<h2>Answers and Solutions</h2>

Q:1 The correct answer is option 1 i.e. 24 days.

From the pie chart:

The ratio of wages received by A, B, C, and D = 16 : 20 : 40 : 24 = 4 : 5 : 10 : 6

We know that the ratio of wages shared will be equal to the ratio of their efficiencies

So,

The ratio of efficiencies of A and B = 4 : 5

Since efficiency and time are inversely proportional:

The ratio of time in which A and B will finish the work working alone = 5 : 4

Now, A alone can complete the work in 30 days.

So,

Time taken by B to complete the work alone = 30 × 4/5 = 24 days

 

Q:2 The correct answer is option 1 i.e. 66.67%.

From the pie chart:

Total wages received by A and D = 16 + 24 = 40%

And,

Total wages received by B and C = 20 + 40 = 60%

Hence,

Required percentage = 40/60 × 100 = 66.67%

 

Q:3 The correct answer is option 3 i.e. 12 days.

From the pie chart:

The ratio of wages received by A, B, C, and D = 16 : 20 : 40 : 24 = 4 : 5 : 10 : 6

We know that the ratio of wages shared will be equal to the ratio of their efficiencies.

So,

The ratio of efficiencies of C and D = 10 : 6

Since efficiency and time are indirectly proportional:

The ratio of time in which C and D will finish the work working alone = 6 : 10

Now, D alone can complete the work in 20 days

So,

Time taken by C to complete the work alone = 20 × 6/10 = 12 days

 

Q:4 The correct answer is option 5 i.e. 15 : 12 : 6 : 10.

From the pie chart:

The ratio of wages received by A, B, C, and D = 16 : 20 : 40 : 24 = 4 : 5 : 10 : 6

We know that the ratio of wages shared will be equal to the ratio of their efficiencies.

So,

The ratio of efficiencies of A, B, C, and D = 4 : 5 : 10 : 6

Since efficiency and time are indirectly proportional:

The ratio of time in which A, B, C, and D will finish the work individually

⇒ 1/4 : 1/5 : 1/10 : 1/6

⇒ 15 : 12 : 6 : 10

 

Q:5 The correct answer is option 4 i.e. Rs. 900.

From the pie chart:

Required difference = [(16 + 40) – (20 + 24)]/100 × 7500 = Rs. 900

 

Q:6 The correct answer is option 5 i.e. 2700.

Total failed student = 12000/2 × 3 = 18000

Required average = 1/2 [(10 + 20)/100] × 18000 = 2700

 

Q:7 The correct answer is option 2 i.e. \(59\frac{1}{11}%\)%.

Required percentage = \(\frac{(20+15)-(10+12)}{10+12} \) x 100

⇒ \(\frac{35-22}{22}\) x 100 = 59\(\frac{1}{11}% \)%

 

Q:8 The correct answer is option 4 i.e. 29,400.

25% of total student = 12,000

Total student = 48,000

Total failed student = 48,000 – 12,000 = 36,000

Total passed student in Computer, Math, and Hindi together

⇒ 55/100 × 12,000 = 6,600

Required difference = 36,000 – 6,600 = 29,400

 

Q:9 The correct answer is option 1 i.e. 11 : 6.

Total passed student in Physics = 15/100 × 12,000 = 1800

Passed student in Chemistry = 10/100 × 12,000 = 1200

Required Ratio = (4000 - 1800)/1200 = 2200/1200 = 11 ∶ 6

 

Q:10 The correct answer is option 2 i.e. 75%.

Passed student in Hindi = 12/100 × 12,000 = 1440

Failed student in Hindi = 1440 × 125/100 = 1800

Passed student in English = 12,000 × 20/100 = 2400

Required percentage = 1800/2400 × 100 = 75%
