Question

Are these numbers in inverse proportion4 upon 5 1 upon 2 1 upon 8 1 upon 4​

Answer 1

Answer:

Two quantities are in inverse proportion only if one of them increases and the other decreases.

i) Inverse proportion ⇒ If number of workers increases, then the time to complete job decreases.

ii) Not Inverse proportion ⇒ If time taken for a journey increases, then the distance travelled at uniform speed remains same.

iii) Not Inverse proportion ⇒ If area of cultivated land increases, then harvested crop will also increase.

iv) Inverse proportion ⇒ If time taken for a fixed journey increases, then the speed of vehicle decreases, so it is in inverse proportion

v) Inverse proportion ⇒ If population of a country increases, then the area of land per person decreases.

∴ (i), (iv) and (v) are in inverse proportion.
