Question

On a particular day the exchange rate of 1 Euro was Rs. 55. The following linear Graph shows the relationship between the two currencies. Read the graph carefully. and answer the questions given below:
(i) Find the values of 4 Euros in terms of Rupees.
(ii) Find the values of 6 Euros in terms of Rupees.
(iii) Find the value of Rs. 275 in terms of Euros.
(iv) Find the value of Rs. 440 in terms of Euros.

Answer 1

- Hint: Start by preparing the x and y axes. Plot Rupees on y-axis and Euros on x-axis with some assumed scale. Draw the linear variation of the exchange rate, Draw horizontal and vertical lines as per the conversion of Rupees to Euros or vice-versa.

Complete step-by-step answer:
(i). Draw a vertical line at x=4 parallel to y-axis intersecting the graph at A and then draw a horizontal line from this point towards y-axis and parallel to x-axis. The value found is Rs 220/- .
(ii). Draw a vertical line at x=6 parallel to y-axis intersecting the graph at B and then draw a horizontal line from this point towards y-axis and parallel to x-axis. The value found is Rs 330/- .
(iii). Draw a horizontal line at y=275 parallel to x-axis intersecting the graph at C and then draw a vertical line from this point towards x-axis and parallel to y-axis. The value found is € 5.
(iv). Draw a horizontal line at y=440 parallel to x-axis intersecting the graph at D and then draw a vertical line from this point towards x-axis and parallel to y-axis. The value found is € 8 .

Note: Ruler and pencil should be used for drawing such graphs. One must mention the scale chosen to draw the graph over the upper right corner and name the graph .
