CCI Management Trainee (Accounts) Mock Test - 5 - Question 3

"Global commodity prices are easing." What does the author mean when he says this?

Detailed Solution for CCI Management Trainee (Accounts) Mock Test - 5 - Question 3

The correct answer is Option 4 i.e. The prices of commodities are decreasing globally.
Key Points

  • The term "easing" in the context of prices generally means that prices are decreasing or becoming less severe.
  • The passage is discussing positive economic signs, and the easing of global commodity prices is highlighted as one such positive indicator.
  • A decrease in global commodity prices would contribute to the overall positive economic outlook by helping to moderate inflation.
  • Therefore, "easing" indicates a downward trend in prices, which aligns with the author's optimistic view of improving economic conditions.

Therefore, the correct answer is The prices of commodities are decreasing globally.
Additional Information

  • Option 1: Commodity prices are increasing day by day. This is incorrect because "easing" implies a reduction, not an increase.
  • Option 2: It is easy to determine global commodity prices today. This is incorrect as "easing" refers to the movement of prices, not the ease of determining them.
  • Option 3: The prices of commodities are changing globally. While this is somewhat true, it is too vague. The passage specifically implies that prices are easing, which means decreasing.

CCI Management Trainee (Accounts) Mock Test - 5 - Question 6

Arun brought 50 kg of rice at a discount of 15% on the marked price. For purchasing bulk quantity, he was given 5 kg of wheat (the marked price of which was 60% the marked price of rice) free of cost. Had the retailer sold both items at their marked price to his other customers, then approximately what would be the profit percentage that the shopkeeper could earn?

Detailed Solution for CCI Management Trainee (Accounts) Mock Test - 5 - Question 6

Given:
Arun brought 50 kg of rice at a discount of 15% on the marked price.
The shopkeeper offered 5 kg of wheat for free.
Formula used:
Profit % = (Profit/Cost price) × 100
Calculation:
Let the cost of rice be Rs. x per kg
Price of 50 kg rice = Rs. 50x
But he bought it at a discount of 15%
Cost Price of rice for arun = Rs. (50x × 85/100 )
= Rs. 42.5x
The price of an extra 5 kg wheat sold at 60% M.p of rice = 5 × 0.6x
= Rs. 3x
Retailer didn’t paid Rs. 3x though he got (50 + 5) kg = 55 kg of weight
But he sold the 55 kg mix at a price Rs. 53x
Profit gained by him = (53x – 42.5x) = 10.5x
Profit percentage = (10.5x/42.5x) × 100
⇒ 24.7 %

∴ The answer is 24.7%.

CCI Management Trainee (Accounts) Mock Test - 5 - Question 7
A boat takes 20 hours for travelling downstream from point A to point B and comes back to a midpoint C between A and B. The speed of the stream is 5 km/h and the speed of the boat in still water is 10 km/h. Find the distance between A and B (in km),
Detailed Solution for CCI Management Trainee (Accounts) Mock Test - 5 - Question 7

Given:

Speed of the stream = 5 km/h

Speed of the boat in still water = 10 km/h

Distance from A to C = Distance from B to C

Time to travel downstream from point A to B and from B to C = 20 hours

Formula Used:

Speed downstream = Speed of boat in still water + Speed of stream

Speed upstream = Speed of boat in still water - Speed of stream

Distance = Speed × Time

Calculation:

Speed downstream = 10 + 5 = 15 km/h

Speed upstream = 10 - 5 = 5 km/h

Let, Distance from point A to B = 2x

So, distance from point A to B = distance from point B to C = 2x/2 = x

Now, according to the given data,

⇒ 2x/15 + x/5 = 20

⇒ (2x + x × 3)/15 = 20

⇒ 5x/15 = 20

⇒ x/3 = 20

⇒ x = 20 × 3 = 60 km

So, Distance between A and C = Distance between B and C = 60 km

So, Total distance = 2 × 60 =120 km

∴ The distance between A and B is 120 km.

CCI Management Trainee (Accounts) Mock Test - 5 - Question 8
A, B, and C invest their capital in the ratio of 2/5 ∶ 3/4 ∶ 5/8. After 3 months, A increased his capital by 25% and B decreased his capital by 20% and C does not make any change in his investment. What is the share (in Rs.) of C in the total profit of Rs. 1,08,420 after one year?
Detailed Solution for CCI Management Trainee (Accounts) Mock Test - 5 - Question 8

Given:

A, B and C start a business with their capitals in the ratio

Calculation:

LCM of 5, 4 and 8 = 40

So, 40 × = 16, 40 × = 30, 40 × = 25

Let the investments of A, B, and C be 16x, 30x and 25x

Capital of A at the end of the year = 16x × 3 + (16x + 16x × 25%) × 9 = 228x

Capital of B at the end of the year = 30x × 3 + (30x - 30x × 20%) × 9 = 306x

Capital of C at the end of the year = 25x × 12 = 300x

Ratio of share of profit = 228x : 306x : 300x

⇒ 38 : 51 : 50

Now,

Share of C = 108420 × (50/139)

⇒ 39000

∴ The share (in Rs.) of C in the total profit of Rs. 108420 after one year is 39000.

CCI Management Trainee (Accounts) Mock Test - 5 - Question 9

Pipes A and B can fill a tank in 30 hours and 45 hours, respectively while pipe C alone can empty the full tank in 20 hours. When the tank is full, C alone is opened for 8 hours and then closed and pipes A and B are opened together at the same time. Now, how much time will pipes A and B together take to fill the tank completely?

Detailed Solution for CCI Management Trainee (Accounts) Mock Test - 5 - Question 9

Given:

Pipe A can fill a tank in 30 hours

Pipe B can fill a tank in 45 hours

C alone can empty the full tank in 20 hours

Calculations:

Let the total work be 1

Work done by A in 1 hour = 1/30 units

Work done by B in 1 hour = 1/45 units

Work done by C in 1 hour = -1/20 units ----(-ve sign shows that it is emptying the tank)

Work done by C in 8 hour = -8/20 = -2/5 units ----(-ve sign shows that it is emptying the tank)

Work done by (A + B) to fill 2/5 tank emptied by C

⇒ 1/30 + 1/45 = 2/5 of tank

⇒ (3 + 2)/90 = 2/5

⇒ 1/18 = 2/5

⇒ (2/5) × 18 = 7.2 hours

∴ The time taken by pipes A and B together take to fill the tank completely is 7.2 hours.

CCI Management Trainee (Accounts) Mock Test - 5 - Question 10
A boat can cover a distance of 56 km downstream in 3.5 hours. The ratio of the boat in still water and the speed of stream is 3 : 1. How much time (in hours) will the boat take to cover a distance of 41.6 km downstream?
Detailed Solution for CCI Management Trainee (Accounts) Mock Test - 5 - Question 10

Given:

A boat can cover a distance of 56 km downstream in 3.5 hours

The ratio of the boat in still water and the speed of the stream is 3 : 1

Concept used:

Speed = D/T

D = distance

T = time

Calculation:

Speed of the boat downstream = 56/3.5

⇒ 16 km/h

Now,

To cover 41.6 downstream it will take = 41.6/16 hours

⇒ 2.6 hours

The boat will take 2.6 hours to cover a distance of 41.6 km downstream.

Additional InformationHere we do not need to calculate the speed of the boat in still water and the speed of the stream individually, as in the question the operations were asked downstream.

CCI Management Trainee (Accounts) Mock Test - 5 - Question 11
The average age of A, B and C, 5 years ago, was 32 years. The average age of B and C, 6 years ago, was 28.5 years. A will retire at the age of 60. After how many years from now will he retire?
Detailed Solution for CCI Management Trainee (Accounts) Mock Test - 5 - Question 11

Given:

The average age of A, B and C, 5 years ago, was 32 years.

The average age of B and C, 6 years ago, was 28.5 years.

Concept used:

Total = Average × Number of entities

Calculation:

Let the present age of A, B and C be denoted by A, B and C.

According to the question,

(A - 5) + (B - 5) + (B - 5) = 32 × 3

⇒ (A + B + C) = 111 ....(1)

(B - 6) + (C - 6) = 28.5 × 2

⇒ (B + C) = 69 ....(2)

(1) - (2) we get,

A = 111 - 69 = 42

A will retire in = (60 - 42) = 18 years

∴ After 18 years from now, A will retire.
