Calculations:
According to the question,
Total Accountants working = Total joined - Total left
Working = (35 + 26 + 15 + 20 + 14) - (16 + 5 + 38 + 24)
Working = 110 - 83 = 27
∴ The total number of accountants working in the organization in the year 2019 is 27.

J1= The average production of A in year Y1 and Y2.
J2 = Sum of production of B, C and D in year Y1 and Y2.
What is the value of (J2/J1)?
Answer (Detailed Solution Below)
Data Question 3 Detailed Solution

J1 = (50 + 100)/2
⇒ 150/2
⇒ 75
J2 = (90 + 120 + 30 + 80 + 80 + 50)
⇒ 450
So, J2/J1 = 450/75
⇒ 6
∴ The required answer is 6.

⇒ (810/7800) × 100 = 10.38
The percentage of candidates that qualified from Goa over those that appeared from Goa in 2013
⇒ (800/7500) × 100 = 10.66
The percentage of candidates that qualified from Goa over those that appeared from Goa in 2014
⇒ (920/8800) × 100 = 10.45
The percentage of candidates that qualified from Goa over those that appeared from Goa in 2015
⇒ (850/7200) × 100 = 11.80
∴ The correct option is 4

So, the number of students who scored marks between 20 and 30 = 6 - 5
⇒ 1
∴ The required answer is 1.

Schools | A | B |
J | 31 | 58 |
K | 24 | 36 |
L | 18 | 26 |
M | 29 | 37 |
N | 12 | 33 |
P | 40 | 44 |
What is the ratio of total number of players participating in game A to the total number of players participating in game B?
Answer (Detailed Solution Below)
Data Question 6 Detailed Solution
Calculation:
Total number of players participating in game A = 31 + 24 + 18 + 29 + 12 + 40
⇒ 154
Total number of players participating in game B = 58 + 36 + 26 + 37 + 33 + 44
⇒ 234
Ratio = 154 : 234
⇒ 77 : 117
∴ Ther required answer is 77 : 117.
Data Question 7:
Study the given table and answer the question that follows.
The following table shows the population of a city at the end of the years mentioned.
Which of the following years has the highest rate of increase compared to the previous year?
Answer (Detailed Solution Below)
Data Question 7 Detailed Solution
Given:
Data regarding the population of a city at the end of the years mentioned.
Formula used:
Rate of increase = (population in current year - population in previous year) / (population in previous year) × 100
Calculation:
The rate of increase for a given year compared to the previous year can be calculated by using above formula.
Lets calculate the rate of increase for a given year compared to the previous year,
Rate of increase in 2013 = \(\frac{68.4-64.5}{64.5}\times 100\) = 6.04
Rate of increase in 2014 = \(\frac{72.6-68.4}{68.4}\times 100\) = 10.93
Rate of increase in 2015 = \(\frac{83.8-72.6}{72.6}\times 100\) = 15.42
Rate of increase in 2016 = \(\frac{100.6-83.8}{83.8}\times 100\) = 20.4
Rate of increase in 2017 = \(\frac{112.8-100.6}{100.6}\times 100\) = 12.12
Rate of increase in 2018 = \(\frac{128.4-112.8}{112.8}\times 100\) = 13.8
Rate of increase in 2019 = \(\frac{134.6-128.4}{128.4}\times 100\) = 4.82
Rate of increase in 2020 = \(\frac{156.8-134.6}{134.6}\times 100\) = 16.49
Rate of increase in 2021 = \(\frac{176.4-156.8}{156.8}\times 100\) = 12.5
2016 has the highest rate of increase compared to the previous year which is 20.4%
Data Question 8:
The monthly wages (in ₹) of three mess workers, Rahul, Sunil and Vipin, of a boy's hostel for three months are given in the following table. Study the table carefully and answer the question given below.
Mess workers/Month | October | November | December |
---|---|---|---|
Rahul | 10800 | 11500 | 12000 |
Sunil | 10000 | 10500 | 11500 |
Vipin | 10400 | 11600 | 12200 |
In November, the wages of Sunil is what percentage of the wages of Rahul? (Correct up to two decimal places.)
Answer (Detailed Solution Below)
Data Question 8 Detailed Solution
Given:
Wages of Rahul in November = ₹11500
Wages of Sunil in November = ₹10500
Formula used:
Percentage = \(\dfrac{\text{Wages of Sunil}}{\text{Wages of Rahul}} \times 100\)
Calculation:
⇒ Percentage = \(\dfrac{10500}{11500} \times 100\)
⇒ Percentage = \(\dfrac{10500 \times 100}{11500}\)
⇒ Percentage = 91.30%
∴ Sunil's wages in November are 91.30% of Rahul's wages in November.
Data Question 9:

The below table gives shares traded on Hyderabad, Mumbai, and Bengaluru stock exchanges (in ₹). same company, in the stock exchange(s) at _____.
Name of Company | Hyderabad High | Hyderabad Low | Mumbai High | Mumbai Low | Bengaluru High | Bengaluru Low |
A | 150 | 140 | 180 | 165 | 160 | 155 |
B | 250 | 225 | 325 | 315 | 300 | 290 |
C | 180 | 175 | 195 | 180 | 190 | 185 |
D | 350 | 325 | 410 | 395 | 390 | 375 |
"For C, the low rates of shares are less than the average of the low rates of shares of the same company, in the stock exchange(s) at ____."
Answer (Detailed Solution Below)
Data Question 9 Detailed Solution
Calculations:
Step 1: Calculate the average of the low rates for company C:
Low rates: Hyderabad = 175, Mumbai = 180, Bengaluru = 185.
Average = (175 + 180 + 185) / 3 = 540 / 3 = 180.
Step 2: Compare the low rates with the average:
Hyderabad Low: 175 (less than 180).
Mumbai Low: 180 (equal to 180).
Bengaluru Low: 185 (greater than 180).
The low rates of shares for company C are less than the average in the Hyderabad stock exchange.
Data Question 10:
The table below shows the production of three types of cars (A, B and C) manufactured (in thousands) by an automobile company over the years.
Year | A | B | C |
---|---|---|---|
2012 | 1750 | 1880 | 1900 |
2013 | 1800 | 2950 | 2070 |
2014 | 2950 | 3020 | 3150 |
2015 | 3100 | 3240 | 3290 |
The average number of A-type cars produced by the company during 2012 to 2014 is what percent (rounded off to the 1 decimal place) less than the combined average number of B-type and C-type cars produced by the company from 2013 to 2015?
Answer (Detailed Solution Below)
Data Question 10 Detailed Solution
Given:
Production of A-type cars in 2012: 1750 (thousand)
Production of A-type cars in 2013: 1800 (thousand)
Production of A-type cars in 2014: 2950 (thousand)
Production of B-type cars in 2013: 2950 (thousand)
Production of B-type cars in 2014: 3020 (thousand)
Production of B-type cars in 2015: 3240 (thousand)
Production of C-type cars in 2013: 2070 (thousand)
Production of C-type cars in 2014: 3150 (thousand)
Production of C-type cars in 2015: 3290 (thousand)
Calculations:
Calculate the average production of A-type cars (2012-2014):
Average production of A-type cars = (1750 + 1800 + 2950) / 3 = 6500/3
Calculate the combined average production of B-type and C-type cars (2013-2015):
Combined average production of B-type cars and C-type cars
= (2950 + 3020 + 3240 + 2070 + 3150 + 3290) / 6
= 17,720/6 = 8860/3
Calculate the difference between the averages:
Difference = 8860/3 - 6500/3 = 2360/3
Calculate the percentage difference:
Percentage difference = (2360/3 / 8860/3) × 100 = 26.6% (rounded to 1 decimal place)
Therefore, the average number of A-type cars produced by the company during 2012 to 2014 is 26.6% less than the combined average number of B-type and C-type cars produced by the company from 2013 to 2015.
