**I. Study the following table, showing monthly sales of cars of five types by five automobile shops to answer the questions that follow.**

Type | Automobile Shops | ||||

P | Q | R | S | T | |

A | 1250 | 3500 | 1360 | 2240 | 210 |

B | 2100 | 3080 | 3700 | 4200 | 920 |

C | 3460 | 4400 | 4860 | 4860 | 4760 |

D | 900 | 680 | 700 | 1120 | 600 |

E | 300 | 440 | 1200 | 1250 | 280 |

**1.1) Which shop has the lowest sales of both type B and type E as compared to other shops?****(a) P****(b) Q****(c) R****(d) T**

The shop T has the lowest sales of both B-type (920) and E-type (280) cars.**1.2) Which shop has a share of 15% sales of the total type D sold by all the shops?****(a) P****(b) Q****(c) R****(d) T**

15% of 4000 = 600

(do mental calculations to get quick answers. for example, 10% of 4000 is 400 and

5% of 4000 is 200 and then total 600 and then check for 600 in the table)**1.3) Which shop has the highest sale of cars of all the types ?****(a) P****(b) Q****(c) R****(d) S**

**1.4) Which shop sells cars of type B seven times to that of type E sold by it?****(a) Only P****(b) Only Q****(c) Both P and Q****(d) Only T****1.5) Among all the shops, the lowest sale of type A is the highest sale of which of the following types?****(a) B****(b) C****(c) D****(d) E**

For type, A cars the lowest sale is shown by the hop T which has the maximum sale (4760)

of type C cars.**2. Study the following graph carefully and answer the questions given below it.**

**2.1) By what approximate percentage the export of coffee increased from 1996-97 to 1997-98?****(a) 205****(b) 185****(c) 195****(d) 190**

[(525 – 180)/180 ] * 100

= 190%.

**2.2) What is the ratio of the export of coffee in 1994-95 to that in 1996-97?****(a) 69: 85****(b) 23: 30****(c) 85: 69****(d) 30: 23**

= 138: 180

=69:90

= 23:30

**2.3) What was the percentage increase in the export of Tea in 1997-98 from that in 1993-94?****(a) 40****(b) 90****(c) 35****(d) 20**

Percentage increase from previous year to this year = [(Initial – Final)/Initial]*100 = 40%**2.4) By what percent did the export of tea fall in 1994-95 from that in the previous duration?****(a) 1****(b) 2****(c) 4****(d) 3**

Fall in export of Tea in 94-95 = [(150 – 147)/150] * 100 = 2%

**2.5) What was the ratio between export of coffee to tea in 1997 -98?****(a) 5:14****(b) 2:5****(c) 5:2****(d) 14:5**

Ratio of Coffee to tea in 92-98 = 525 : 210

= 5: 2
