Question

true or false (A) the number of workers and the time to complete a job is a case of direct proportion (B) distance traveled by an auto rickshaw and time taken is a case of direct proportion ​

Answer 1

Answer:

(i) We know that more is the number of workers to do a job, less is the time taken to finish the job.

So, it is a case of inverse proportion.

(ii) Considering uniform speed, as the distance to be travelled increases, the time taken to cover it will also increase.

So, this is a case of direct variation.

(iii) Clearly, more is the area of cultivated land, more is the crop harvested.

So, it is a case of direct proportion.

(iv) We know that the more will be the speed of the vehicle, the distance will be covered in lesser time.

So, it is a case of inverse proportion.

(v) Clearly, more is the population, less is the area of land per person in a country.

So, it is a case of inverse proportion.

Answer 2

Given : Statements regarding variation

(A) the number of workers and the time to complete a job is a case of direct proportion

(B) distance traveled by an auto rickshaw and time taken is a case of direct proportion ​

To Find :  True or False

Solution:

Direct variation if a variable increases then other variable also increases with a constant factor   y = kx

inverse variation if a variable increases then other variable decreases with a  constant factor  xy = k

(A) the number of workers and the time to complete a job is a case of direct proportion

As the number of workers increase  , time required to complete the job decreases  as more work is done by more workers

Hence this is inverse proportion

Hence Given statement is FALSE

(B) distance traveled by an auto rickshaw and time taken is a case of direct proportion ​

To Cover more distance more time is needed if speed is constant

Hence distance traveled by an auto rickshaw and time taken is a case of direct proportion ​ TRUE
