Direct & Inverse Proportion Mock Tests

If 5 workers can dig a trench in 20 days, how many days will 10 workers take?

If 12 workers can complete a piece of work in 10 days, how many days will 15 workers take to complete the same work, assuming all work at the same rate?

If 12 workers can build a wall in 15 days, how many days will 20 workers take to build the same wall?

The direct proportion between x and y means:

If a car travels 120 km in 2 hours, how far will it travel in 5 hours at the same speed?

If 15 workers can complete a job in 8 days, how many days will 20 workers take to complete the same job?

If x and y are directly proportional and x = 6 when y = 18, then y when x = 4 is:

If 8 workers can dig a trench in 6 hours, how many hours will 4 workers take?
