# How to solve Line Chart Quickly

Here, In this page How to Solve Line Chart Quickly is given.

### Methods of Solving Line Charts quickly :

This slide is providing the best method of solving the line charts . It has many advantages and disadvantages for solving the line charts better. Students has to carefully study the line chart and predict its data for calculating the questions easily .

Line Charts should have all the measures and steps to clearly analyse the questions and follow the details properly.

- We will simply take all values and calculate the answers.
- This approach rests on the assunmption of blocks.
- It simplifies our calculations signifucantly .

**Directions to Solve**

#### Answer the questions based on the given line graph.

Ratio of Exports to Imports (in terms of money in Rs. crores) of Two Companies Over the Years.

### Question 1.

**In how many of the given years were the exports more than the imports for Company A?**

## Question 2.
We shall try to find the difference between the imports and exports of Company B for various years one by one: For 1995: We have \frac{E}{I} = 0.75where
Thus, the difference between the imports and exports of Company B in 1995 is dependent on the amount of imports of Company B in 1995. Similarly, the difference for other years can be determined only if the amount of imports for these years is known. Since the imports or exports for various years are not know, the differences between and exports for various years cannot be determined. |

## Question 3.
[where E In 1995 for Company B we have: \frac{E_{B}}{I_{B}} =0.75 |

[where E_{B} = amount of exports, I_{B} = amount of imports of Company B in 1995]

Also, we have E_{A} = 2E_{B} … (iii)

Substituting I_{A} = Rs. 180 crores (given) in (i), we get:

E_{A} = Rs. (180 x 1.75) crores = Rs. 315 crores.

Using E_{A} = Rs. 315 crores in (iii), we get:

E_{B} = \frac{E_{A}}{2} = \frac{315}{2} crores

Substituting E_{B} = \frac{315}{2} crores in (ii) we get

I_{B} = \frac{E_{B}}{0.75} = Rs \frac{315}{2 \times 0.75} = 210 crores

i.e., amount of imports of Company B in 1995 = Rs. 210 crores.
