Question

What number when decreased by 5% becomes 665.​

Answer 1

Given: When a number is decreased by 5% it becomes 665.

To find: We have to find out the number.

Solution:

Let the number is 100.

If it is decreased by 5% then 100 will decrease by 5 and the resultant number will be (100-5=95).

But given that the resultant number will be 665.

95 will be equivalent to 665

100 will be equivalent to

$\frac{665}{95} \times 100 \\ = 700$

So, the number is 700.
