Common Calculation

Calculation

Girls in D : F = 7 : 8
Girls in D = 210

⇒ Let girls in F = [8/7] × 210 = 240

Boys in C : F = 8 : 9
Boys in C = 160

⇒ Boys in F = [160/8 ] × 9 = 180 

Total students in F = Girls + Boys = 240 + 180 = 420

Common Calculation

Calculation

Total boys in all schools (A to E) =
140 + 120 + 160 + 170 + 220 = 810

Total schools = 5

Average boys = [810/5] = 162
⇒ m= 162/5 = 32.4,

So, m = 32.4

Common Calculation

Calculation

Girls in C and D = 200 + 210 = 410

Boys in C and D = 160 + 170=330

Difference = 410 – 330 = 80​

Common Calculation

Calculation

Total girls in school B = 160

40% of girls participate in inter-school = 40% × 160 = 64

Total students participating = 144

Boys participating = 144 − 64 = 80

Total boys in school B = 120

Boys not participating = 120 – 80 = 40

Common Calculation

Calculation

Ratio of students using school bus to those not using it = 5:3

Total students in School A = 320

So, let students using school bus = [5/8] × 320 = 200

Those not using school bus = 320 – 200 = 120

Out of those who use the school bus, 50% are girls

⇒ girls = [50 / 100] ×200=100

So, boys who use the bus = 100

Total boys in A = 140

So, boys not using the bus = 140 – 100 = 40

Calculation: 

Let the total number of calls be 1000z.

Initial calls (% out of total calls) of A = (1000z × 40/100) = 400z

Initial calls (% out of total calls) of B = (1000z × 30/100) = 300z

Initial calls (% out of total calls) of C = (1000z × 30/100) = 300z

Lead calls (% out of initial calls) of A = (400z × 80/100) = 320z

Lead calls (% out of initial calls) of B = (300z × x/100) = 3zx

Lead calls (% out of initial calls) of C = (300z × 88/100) = 264z

Final received calls (% out of lead calls) of A = (320z × 90/100) = 288z

Final received calls (% out of lead calls) of B = (3zx × 80/100) = 3zx × (4/5)

Final received calls (% out of lead calls) of C = (264z × y/100)

Total number of initial calls in the company = 24000

⇒ (400z + 300z + 300z) = 24000

⇒ 1000z = 24000

⇒ z = (24000/1000)

⇒ z = 24

Total number of calls not received calls by C = (300h – 264z × y/100)

⇒ (300 × 24 –  264z × y/100)

⇒ (7200 – 264z × y/100)

According to the question

Total number of calls not received by company C is 4464 less than the total number of calls received by company A

⇒ (7200 – 264z × y/100) + 4464 = 288z

⇒ (7200 – 264 × 24 × y/100) + 4464 = 288 × 24

⇒ 7200 – 6336y/100 + 4464 = 6912

⇒ (720000 – 6336y + 446400)/100 = 6912

⇒ (720000 – 6336y + 446400) = 6912 × 100

⇒ (1166400 – 6336y) = 691200

⇒ (-6336y) = (691200 – 1166400)

⇒ (-6336y) = -475200

⇒ y = [-475200/(-6336)]

⇒ y = 75

∴ The value of y is 75

Calculation:

Number less than 200 = 12

Number less than 250 = 26

Number less than between 250 and 200 = (26 – 12)

⇒ 14

Again,

Number less than 250 = 26

Number less than 300 = 34

Number less than between 300 and 250 = (34 – 26)

⇒ 8

Persons earn Rs. 200 or more but less than Rs. 300 = (14 + 8)

⇒ 22

∴ Required persons is 22

Calculation:

Number of families having 1 member = 5

Total members = 5

Number of families having 2 members = 30

Total members = 60

Number of families having 3 members = 45

Total members = 135

Number of families having 4 members = 40

Total members = 160

Number of families having 5 members = 25

Total members = 125

Number of families having 6 members = 5

Total members = 30

So, the total membes in all types of families = 5 + 60 + 135 + 160 + 125 + 30 = 515

Total number of families = 5 + 30 + 45 + 40 + 25 + 5 =150

The average family size = 515 / 150 = 3.4

Hence, option 3 is correct.

Calculation:

Total fund got by school = 100% = 1000000

Funds got through donation = 35%

Scholarship paid = 26% 

Required percentage = 26/35 × 100

⇒ 2600/35 = 74.285% ≈ 74.29%

∴ The correct answer is 74.29%.

Number of registration of vehicles other than bikes in January 2017 = 27,000 - 21,000 = 6,000

Number of registration of vehicles other than bikes in April 2017 = 35,000 - 20,000 = 15,000

∴ the increase in the registration of vehicles other than bikes in April 2017 in comparison of Jan 2017 = 15,000 - 6,000 = 9,000

Calculation

We  have 20% of 50 = 10

Therefore Required number:

Number of students scoring less than 10 marks in aggregate

= 100 - Number of students scoring 10 and above marks in aggregate

= 100 - 87

= 13.

The number of students scoring less than 20% marks in aggregate is 13.

Calculation:

Let the Cost price of the book be 100

Then, Marked Price of the book is 100 + (15% of 100) = 115

Printed price or marked price = 942

Cost price of book = 942 × (100/115)

⇒ 819.13

Now,

Paper cost = 819.13 × 15/100

⇒ 122.869 ≈ 122.9

∴ The required answer is Rs. 122.9

GIVEN:

From the chart

Profit percentage in P5 = 8%

Expenditure = Rs. 46000

FORMULA USED:

Profit percentage = [(Revenue – Expenditure)/Expenditure] × 100

CALCULATION:

Profit percentage = [(Revenue – Expenditure)/Expenditure] × 100

⇒ 8 = [(Revenue – 46000)/46000] × 100

⇒ Revenue – 46000 = 8 × 460

⇒ Revenue = 3680 + 46000

Calculation:

Total cooler sold by shop E = 4000 × (1/10)

⇒ 400

Selling price of 400 coolers = 400 × 8000

⇒ 3200000

Total ACs sold by shop E = 4000 × (5/10)

⇒ 2000

Selling price of 2000 ACs = 2000 × 26500

⇒ 53000000

Total Fans sold by shop E = 4000 × (4/10)

⇒ 1600

Selling price of 1600 Fans = 1600 × 12200

⇒ 19520000

Now,

Required % = [3200000/(3200000 + 53000000 + 19520000)] × 100

⇒ [3200000/(75720000)] × 100

⇒ 4.226 ≈ 4.23%

∴ The required answer is 4.23%.

Calculation:

Total visitors = Male visitors + Female visitors

= 2000 + 1500

= 3500

The total visitors in the age group 25 - 35 is = 27% of 3500 = 945

so

The number of male visitors in the age group 25 - 35 is = 60% of 945 = 567

Similarly,

The total visitors in the age group 45 - 60 is = 29% of 3500 = 1015

so

The number of female visitors in the age group 45 - 60 is = 20% of 1015 = 203

The expected ratio will be,

567 : 203

⇒ 81: 29

∴ The correct option is 4
