Percentages Practice Questions

Percentages Practice Questions section is here and it is time to start the much-needed practice for this section. Here in the Percentages Practice Questions, we have all the different types of questions that can be asked from this section. Best of luck, let us begin!

Percentages Practice Questions

Let us recall the important formulae that we need to solve this section:

(i) To express x% as  fraction: We have x% = x/00. Thus, 20% = 20/100 = 1/5: 48% = 48/100 and so on.

(ii) To express a/b as a percent: We have, a/b as [(a/b)×100]%. Thus, 1/4 can be written as [(1/4)×100]% = 25% etc.

(iii) If the price of a commodity increases by R%, then the reduction in consumption so as not to increase the expenditure is [{R/(100+R)}×100]%.

If the price of a commodity decreases by R%, then the increase in consumption so as not to decrease the expenditure is = [{R/(100-R)}×100]%

(iv) Results on Population: Let the population of a town be P now and suppose it increases at the rate of R% per annum, then:

  1. Population after n years = P[1 + (R/100]n
  2. Population n years ago = P/[1 + (R/100)]n

(v) Results on Depreciation: Let the present value of machine be P. Suppose it depreciates at the rate of R% per annum. Then:

  1. Value of the machine fter n years = P[1 – (R/100)]n
  2. Value of the machine n years ago = P/[1 – (R/100)]n

(vi) If A is R% more than B, then B is less than A by [{R/(100+R)}×100]%.

If A is R% less than B, then B is more than A by [{R/(100 – R)}×100]%.
