NOTE: To solve these questions You need to learn some speed maths tricks in doing fast additions, multiplications, and percentages.
I. Study the following table, showing monthly sales of cars of five types by five automobile shops to answer the questions that follow.
1.1) Which shop has the lowest sales of both type B and type E as compared to other shops?
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?
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 ?
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?
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?
[(525 – 180)/180 ] * 100
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
2.3) What was the percentage increase in the export of Tea in 1997-98 from that in 1993-94?
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?
Fall in export of Tea in 94-95 = [(150 – 147)/150] * 100 = 2%
