Common Calculation

Total number of populations in village A is 240.

Let number of female in village A is 3x

Number of male in village A is 3x × 166.66/100 = 5x

So, 8x = 2400, x = 300

Number of males in village A is 5 × 300 = 1500

Number of females in village A is 3 × 300 = 900

Similarly, we can calculate the others values also.

Calculation

Village D difference = t = 1200 − 800 = 400

Village C difference = x = 1600 − 1000 = 600

So, 7t + 8x = [7 × 400] + [8 × 600] = 2800 + 4800 = 7600

Common Calculation

Total number of populations in village A is 240.

Let number of female in village A is 3x

Number of male in village A is 3x × 166.66/100 = 5x

So, 8x = 2400, x = 300

Number of males in village A is 5 × 300 = 1500

Number of females in village A is 3 × 300 = 900

Similarly, we can calculate the others values also.

Calculation

Males in B + C = 1200 + 1600 = 2800

Females in D + E = 800 + 1000 = 1800

Required % = [2800/1800] × 100 = 155.56%

Common Calculation

Total number of populations in village A is 240.

Let number of female in village A is 3x

Number of male in village A is 3x × 166.66/100 = 5x

So, 8x = 2400, x = 300

Number of males in village A is 5 × 300 = 1500

Number of females in village A is 3 × 300 = 900

Similarly, we can calculate the others values also.

Calculation

Males in A + B = 1500 + 1200 = 2700

Females in C + D = 1000 + 800 = 1800

Difference = 2700 - 1800 = 900

So, 900 = 5x

So, x = 900/5 =180

Common Calculation

Total number of populations in village A is 240.

Let number of female in village A is 3x

Number of male in village A is 3x × 166.66/100 = 5x

So, 8x = 2400, x = 300

Number of males in village A is 5 × 300 = 1500

Number of females in village A is 3 × 300 = 900

Similarly, we can calculate the others values also.

Calculation

Females in B = 1800 → Govt employees = 40% = 0.4 × 1800 = 720

Males in B = 1200 → Private employees = 55% = 0.55 × 1200 = 660

Difference = 720 - 660 = 60

Common Calculation

Total number of populations in village A is 240.

Let number of female in village A is 3x

Number of male in village A is 3x × 166.66/100 = 5x

So, 8x = 2400, x = 300

Number of males in village A is 5 × 300 = 1500

Number of females in village A is 3 × 300 = 900

Similarly, we can calculate the others values also.

Calculation

Males in F = Average of A and E males

= (1500 + 800) / 2 = 2300 / 2 = 1150

Females in F = Average of B and D females

= (1800 + 800) / 2 = 2600 / 2 = 1300

Total population of F = 1150 + 1300 = 2450

Calculation:

The ratio of number of car A and car B in 2012 = 17 : 16

The production of car A in 2012 = 850

Let the ratio of number of car A and car B be 17x and 16x respectively

⇒ 17x = 850

⇒ x = 50

The production of car B = 16x = 16 × 50 = 800

The number of car A manufactured in 2014 = 630

Required ratio = (800 : 630)

⇒ 80 : 63

∴  The ratio of number of Car B manufactured in 2012 to the number of Car A manufactured in 2014 is 80 : 63

Let the total number of employees in the the year 2005 be x

So, the total number of managers in 2005 = (80/100) × x = 0.8x

⇒ Total number of workers in 2005 = x – 0.8x = 0.2x

Hence, the number of male managers in 2005 = (5/8) × 0.8x = 0.5x

And the total number of employees in the the year 2006 be y

Also, So, the total number of managers in 2006 = (50/100) × y = 0.5y

⇒ Total number of workers in 2006 = y – 0.5y = 0.5y

Hence, the number of male managers in 2006 = (2/5) × 0.5y = 0.2y

As the number of workers is the same, we get:

0.2x = 0.5y

⇒ x = 2.5y      ----(i)

Using equation(i), the required ratio will become:

(0.5 × 2.5y)/0.2y = 25/4

∴ The reuqired ratio between the number of male managers in 2005 and 2006 is 25 ∶ 4

Given :

The students joined and left in different years 

Intial strength of school = 2000

Calculation :

Strength of school at the end of 2017 = 2000 + (375 - 250) + (350 - 425) + (400 - 220)

⇒ 2000 + 125 - 75 + 180 = 2230

∴ The answer is 2230.

Formula used:

Percentage = (Part value/Original value) × 100

Calculation: 

Orders placed and delivered on Wednesday

⇒ 400 + 223 = 623

Orders placed and returned on Friday

⇒ 275 + 59.43

⇒ 334.43

Percentage

⇒ (623/334.43) × 100

⇒ 186.70% ≈ 186%

∴ The approximate percentage is 186%.

Calculation:

Total items returned on Tuesday and Wednesday = (60.75 + 28.99) thousand = 89740

Average of items returned on Tuesday and Wednesday = 89740/2 = 44870

∴ 44870

Required average = Sum of observations/number of observations

Females in the month June = 250 × 50/100 = 125

Females in the month July = 200 × 20/100 = 40

The average of the female in the month of June and July by Driver A = (125 + 40)/2 = 82.5

Percentage of males in the month June = 100 - 70 = 30

Males in the month June = 350 × 30/100 = 105

Percentage of males in the month of July = 100 - 40 = 60

Males in the month July = 250 × 60/100 = 150

The average of the Males in the month of June and July by Driver B = (105 + 150)/2 = 127.5

 The ratio of the average of the female in the month of June and July by Driver A to the average of the males in the same month by Driver B

= 82.5 : 127.5 = 11 : 17

Let the number of employees in the company during each of the year be x

So, the number of managers in the year 2005 = (80/100)x = 0.8x

Among them, the number of male managers = (5/8) × 0.8x = 0.5x

Similarly,

So, the number of managers in the year 2006 = (50/100)x = 0.5x

Among them, the number of male managers = (2/5) × 0.5x = 0.2x

So, the percentage decrease in the number of male managers = [(0.5x – 0.2x)/0.5x] × 100 = 60%

Given: Number of delivered orders after cancellation of C = 15

Ratio of cancelled orders of C and E  = 5 : 6

Total number of cancelled orders for C = Total number of delivered orders for C 

Percentage of delivered orders of E = 80%

Calculation: 

Number of cancelled order of C = 15

Number of cancelled order of E = 15/5 × 6 = 18

Percentage of cancelled orders of E = 20%

Total number of orders of E = 18/20 × 100 = 90

Calculations:

From the line graph given, we can get the total population of villages (M, N, O, P, Q ,and R).

From the table provided, We can find 4 parameters only:

1. Literate people of a particular village (Ratio of literate to illiterate)

2. Illiterate people of a particular village (Ratio of literate to illiterate)

3. Male population of a particular village (Percentage of male population)

4. Female population of a particular village (Percentage of male population)

All Data that can be derived from the Line graph and Tabulation is summarised below.

As we can see from the data we can't infer number of literate males.

Hence, The ratio can't be determined  

Individual Solution:

We can not find ratio of literate and illiterate male From M,N and O.

⇒ Male from village P, Q and R = 2000 + 2200 + 1800 = 6000

∴ The ratio can't be determined
