Percentages

Short Cut Methods for solving the questions of Percentages

  1. When any value increases by
    1. 10%, it becomes 1.1 times of itself. (since 100+10 = 110% = 1.1)
    2. 20%, it becomes 1.2 times of itself.
    3. 36%, it becomes 1.36 times of itself.
    4. 4%, it becomes 1.04 times of itself.

Thus we can see the effects on the values due to various percentage increases.

  1. When any value decreases by
    1. 10%, it becomes 0.9 times of itself. (Since 100-10 = 90% = 0.9)
    2. 20%, it becomes 0.8 times of itself
    3. 36%, it becomes 0.64 times of itself
    4. 4%, it becomes 0.96 times of itself.

Thus we can see the effects on a value due to various percentage decreases.

1. When a value is multiplied by a decimal more than 1 it will be increased and when multiplied by less than 1 it will be decreased.

2. The percentage increase or decrease depends on the decimal multiplied.
