*Directions to Solve*

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 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.

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

__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 3,50,000 = 30% of 3,50,000 = 1,05,000.

Q = (45 - 30)% of 3,50,000 = 15% of 3,50,000 = 52,500.

R = (65 - 45)% of 3,50,000 = 20% of 3,50,000 = 70,000.

S = (75 - 65)% of 3,50,000 = 10% of 3,50,000 = 35,000.

T = (90 - 75)% of 3,50,000 = 15% of 3,50,000 = 52,500.

U = (100 - 90)% of 3,50,000 = 10% of 3,50,000 = 35,000.

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

P = (40 - 0)% of 4,40,000 = 40% of 4,40,000 = 1,76,000.

Q = (60 - 40)% of 4,40,000 = 20% of 4,40,000 = 88,000.

R = (75 - 60)% of 4,40,000 = 15% of 4,40,000 = 66,000.

S = (85 - 75)% of 4,40,000 = 10% of 4,40,000 = 44,000.

T = (95 - 85)% of 4,40,000 = 10% of 4,40,000 = 44,000.

U = (100 - 95)% of 4,40,000 = 5% of 4,40,000 = 22,000.

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

= (105000 + 52500 + 52500)

= 2,10,000.

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 4,40,000

= 1,32,000.

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.

Total number of S type cars which remained unsold

= 15% of (35,000 + 44,000)

= 15% of 79,000

= 11,850.

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

For P = | (176000 - 105000) | x 100 | % = 67.62%, rise. | ||

105000 |

For Q = | (88000 - 52500) | x 100 | % = 67.62%, rise. | ||

52500 |

For R = | (70000 - 66000) | x 100 | % = 5.71%, fall. | ||

70000 |

For S = | (44000 - 35000) | x 100 | % = 25.71%, rise. | ||

35000 |

For T = | (52500 - 44000) | x 100 | % = 16.19%, fall. | ||

52500 |

For U = | (35000 - 22000) | x 100 | % = 37.14%, fall. | ||

35000 |

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