Question 1

For the candidates from which of the following locations was there continuous increase both in appeared and passed?

Accepted Answer

As we can see in the graph that metropolises location has continuous increase both in appeared and passed.

Question 2

In which of the following years was the percentage passed to appeared candidates from semi-urban area the least?

Accepted Answer

Our intelligent observation says that the required year cannot be 1993, 1994, 1995. Why? Because see the following conclusions: % passed to appear = Passed / Appeared x 100 % of passed to appear is least when Passed / Appeared is the least or, Appeared / Passed is the most. Now, we do the further calculations mentally. See the following conclusions: For 1990: 7894 / 2513 ⇒ Quotient = 3 and Remainder ≈ 300 For 1991: 8562 / 2933 ⇒ Q = 3 and R ≈ 400 For 1992: 8139 / 2468 ⇒ Q = 3 and R ≈ 800 Similarly, for 1993; 1994, 1995, Q is 2. So, 1992 gives the highest value.

Question 3

What approximate value was the percentage drop in the number of semi-urban candidates appeared from 1991 to 1992?

Accepted Answer

Question 4

In 1993 percentage of candidates passed to appeared was approximately 35 from which location?

Accepted Answer

We do not need to calculate the values for each year. Follow as: For Rural area : 35% of 5032 ≈ 35 × 50 = 1750 ≈ 1798 For Semi-urban area : 35% of 9500 ≈ 35 × 95 ≈ 3300 Which cannot be approximated to 3500. For State capitals : 35 × 85 = 3000 For Metropolises : 35 × 110 = 3850

Question 5

The total number of candidates passed from Rural in 1993 and Semi-urban in 1990 was exactly equal to the total number of candidates passed from State capital in which of the following years?

Accepted Answer

The total number of candidates passed = Candidates passed from Rural in 1993 + Candidates passed from Semi-urban in 1990 The total number of candidates passed = 1798 + 2513 = 4311. From the given table graph check the number of passed candidate from state capital is 4311 which is 1994.

Question 6

What was the difference between the number of B type tyres manufactured in 1994 and 1995?

Accepted Answer

Required difference = Number of B type tyres in 1994 - Number of B type tyres in 1995 Required difference = ( 27.5 − 22.5 ) Million = 5 Million = 5000000.

Question 7

The total number of all the three types of tyres manufactured was the least in which of the following years?

Accepted Answer

Only by visual observation you can find the answer. You do not need to calculate the values. I (iv) (e) Production of B type cars is more than the production of C type cars only in 1993, 1994 and 1995. We see the largest difference exists in 1995. So, the answer is 1995.

Question 8

Accepted Answer

Question 12

What is the ratio of the total sales of Branch B 2 for both the years to the total sales of Branch B 4 for both the years?

Accepted Answer

∴ Required ratio = the ratio of the total sales of Branch B2 in 2000 and 2001 years : the ratio of the total sales of Branch B4 in 2000 and 2001 years the ratio of the total sales of Branch B2 in 2000 and 2001 years = 75 + 65 = 140 the ratio of the total sales of Branch B4 in 2000 and 2001 years = 85 + 95 = 180 Required ratio = 140:180 = 7:9

Question 13
