GaryK [48]

Answer:

Jack must Answer minimum 28 question correctly in order to get A in Science.

Step-by-step explanation:

Given:

Percentage required = 92%

Total Number of question = 30

We need to find the number of Question answer correctly.

Solution:

number of Question answer correctly be 'x'

So we can say that;

number of Question answer correctly divided by Total Number of question multiplied by 100 should be greater than or equal to percentage required.

framing in equation form we get;

$\frac{x}{30}\times 100\geq 92\\\\\frac{10x}{3}\geq 92$

Now Dividing both side by $\frac{3}{10}$ we get;

$\frac{3}{10}\times \frac{10x}{3}\geq 92\times \frac3{10}\\\\x\geq 27.2$

Hence Jack must Answer minimum 28 question correctly in order to get A in Science.
