8.Answer: 12
Step 1: In the given case Output Value is 80.
Step 2: Let us consider the unknown value as x.
Step 3: Consider the output value of 80 = 100%.
Step 4: In the Same way, x = 15%.
Step 5: On dividing the pair of simple equations we got the equation as under
80 = 100% (1).
x = 15% (2).
(80%)/(x%) = 100/15
Step 6: Reciprocal of both the sides results in the following equation
x%/80% = 15/100
Step 7: Simplifying the above obtained equation further will tell what is 15% of 80
x = 12%
Therefore, 15% of 80 is 12
9. Answer: 300
Step-by-step explanation:
We have, 4% × x = 12
or,
4
100
× x = 12
Multiplying both sides by 100 and dividing both sides by 4,
we have x = 12 ×
x = 300
10. Answer: 40
To find percentage, we need to find an equivalent fraction with denominator 100. Multiply both numerator & denominator by 100
3075 × 100100
= (30 × 10075) × 1100 = 40100
Therefore, the answer is 40%
If you are using a calculator, simply enter 30÷75×100 which will give you 40 as the answer.
