Percentage of Six different types of Cars manufactured by a Company over Two Years

For which model is the percentage rise/fall in production from 2000 to 2001 the minimum?

A.

Q

B.

R

C.

S

D.

T

Correct answer is B

The percentage change (rise/fall) in production from 2000 to 2001 for various models is:

For P = [ (176000 - 105000)/105000 x 100 ] % = 67.62%, rise.

For Q = [ (88000 - 52500)/52500 x 100 ] % = 67.62%, rise.

For R = [ (70000 - 66000)/70000 x 100 ] % = 5.71%, fall.

For S = [ (44000 - 35000)/35000 x 100 ] % = 25.71%, rise.

For T = [ (52500 - 44000)/52500 x 100 ] % = 16.19%, fall.

For U = [ (35000 - 22000)/35000 x 100 ] % = 37.14%, fall.

Therefore Minimum percentage rise/fall in production is the case of model R.

The bar graph given below shows the percentage distribution of the total production of a car manufacturing company into various models over two years.

Percentage of Six different types of Cars manufactured by a Company over Two Years

If 85% of the S type cars produced in each year were sold by the company, how many S type cars remain unsold?

A.

7,650

B.

9,350

C.

11,850

D.

12,250

Correct answer is C

Number of S type cars which remained unsold in 2000 = 15% of 35,000

and number of S type cars which remained unsold in 2001 = 15% of 44,000.

Therefore Total number of S type cars which remained unsold

    = 15% of (35,000 + 44,000)

    = 15% of 79,000

    = 11,850.

The bar graph given below shows the percentage distribution of the total production of a car manufacturing company into various models over two years.

Percentage of Six different types of Cars manufactured by a Company over Two Years

If the percentage production of P type cars in 2001 was the same as that in 2000, then the number of P type cars produced in 2001 would have been?

A.

140,000

B.

132,000

C.

117,000

D.

105,000

Correct answer is B

If the percentage production of P type cars in 2001

    = Percentage production of P type cars in 2000

    = 30%.

then, number of P type cars produced in 2001

    = 30% of 440,000

    = 132,000.

The bar graph given below shows the percentage distribution of the total production of a car manufacturing company into various models over two years.

Percentage of Six different types of Cars manufactured by a Company over Two Years

Total number of cars of models P, Q and T manufactured in 2000 is?

A.

245,000

B.

227,500

C.

210,000

D.

192,500

Correct answer is C

Analysis of the graph:

We shall first determine the number of cars of each model produced by the Company during the two years:


In 2000 : Total number of cars produced = 3,50,000.

P = (30 - 0)% of 350,000 = 30% of 350,000 = 105,000.

Q = (45 - 30)% of 350,000 = 15% of 350,000 = 52,500.

R = (65 - 45)% of 350,000 = 20% of 350,000 = 70,000.

S = (75 - 65)% of 350,000 = 10% of 350,000 = 35,000.

T = (90 - 75)% of 350,000 = 15% of 350,000 = 52,500.

U = (100 - 90)% of 350,000 = 10% of 350,000 = 35,000.


In 2001 : Total number of cars produced = 4,40,000.

P = (40 - 0)% of 440,000 = 40% of 440,000 = 176,000.

Q = (60 - 40)% of 440,000 = 20% of 440,000 = 88,000.

R = (75 - 60)% of 440,000 = 15% of 440,000 = 66,000.

S = (85 - 75)% of 440,000 = 10% of 440,000 = 44,000.

T = (95 - 85)% of 440,000 = 10% of 440,000 = 44,000.

U = (100 - 95)% of 440,000 = 5% of 440,000 = 22,000.


Total number of cars of models P, Q and T manufacture in 2000

    = (105000 + 52500 + 52500)

    = 210,000.

Percentage of Six different types of Cars manufactured by a Company over Two Years

What was the difference in the number of Q type cars produced in 2000 and that produced in 2001?

A.

35,500

B.

27,000

C.

22,500

D.

17,500

Correct answer is A

Total number of Q type cars produced in 2001

=(60 - 40)% of 4,40,000 = 88,000.

Total number of Q type cars produced in 2000

=(45 - 30)% of 3,50,000 = 52,500.

Therefore Required difference = (88000 - 52500) = 35,500.
