Question
A number N undergoes a two-step adjustment: first, it is
increased by 20%, and then it is subsequently decreased by 10% of the new value. After these adjustments, the final result is 1,080. Determine the original value of the number N before any changes were applied.Solution
When there are two changes then, we can find resultant change by given method- -Constable/1731125039-257.JPG)
= +8%, here positive sign shows the increasing. Let original number was 100% Then 108% = 1080 Original number = 100% = 1080/108 × 100 = 1000
