Find the missing figures: ?% of 25 = 2.125
- Let a% of 25 = 2.125. Then , (a/100) x 25 = 2.125 a = (2.125 x 4) = 8.5
To find the missing figure in the given equation, we need to use the concept of percentages and solve for the unknown percentage.
We are given that "?% of 25 = 2.125". This means that some percentage of 25 is equal to 2.125. We can write this as an equation:
(?/100) x 25 = 2.125
To solve for the unknown percentage, we can isolate the variable "?". First, we simplify the left-hand side by multiplying 25 and "?/100". This gives:
(25 ?)/100 = 2.125
We can further simplify this equation by multiplying both sides by 100, which gives:
25 ? = 212.5
Finally, we can solve for "?" by dividing both sides by 25, which gives:
? = 8.5
Therefore, the missing figure in the given equation is 8.5.
Hence, the correct answer is option B.
