Question

To carry a bag of 50kg rice at the distance of 4

km a porter charges Rs.75. How much does the
porter charge at the same rate to carry a bag of
80kg rice to the distance of 10km?
b. 500
d. 700
a. 400
c. 600

Answer 1

The porter charges Rs 300 at this rate.

Explanation:

We solve this question by proportions, using rule of three.

75 Rs - 4 km - 50 kg

x Rs - 10 km - 80 kg

Relationship between the variables:

As the distance, or the weight increase, the rate will increase. This means that:

`(75)/(x) = (4*50)/(10*80)`

`(75)/(x) = (200)/(800)`

`(75)/(x) = (2)/(8)`

`x = (75*8)/(2) = 75*4 = 300`

The porter charges Rs 300 at this rate.
