Q. A bank gives 10% Simple Interest (S.I.) on deposits by senior citizens. Draw a graph to
illustrate the relation between the sum deposited and simple interest earned. Find from
your graph

Try a case of direct variation?

 

Taking a case of direct variation the graph is as shown below. Taking sum deposite as 100,200,300,500 ,1000.  and  10% Simple Interest (S.I.).    

Q.1 In the above example, use the graph to find how much petrol can be purchased
for  Rs 800.

From the graph given below we can say that for  Rs 800 we can buy 16 litres.  

Q.4 State whether True or False. Correct
that are false. 

(iii) The coordinates of the origin
are (0, 0).

(iii)True. The coordinates of the origin are (0, 0).

Q.4 State whether True or False. Correct that are false.

(ii) A point whose y coordinate is zero and x-coordinate is 5 will lie on
y-axis.

 

(ii) False.Point  does not lie on y-axis.A point whose y coordinate is zero and x-coordinate is 5 will not lie on y-axis.

Q.4 State whether True or False. Correct that are false.
(i) A point whose x coordinate is zero and y-coordinate is non-zero will
lie on the y-axis.

 

(i) True .A point whose x coordinate is zero and y-coordinate is non-zero will lie on the y-axis. =  here, y is variable.
