Question

Kiran scored $80$ marks in his Science test which is $\frac{5}{6}$ of the total marks. What are the total marks for the test?

• A. $96$
• B. $100$
• C. $104$
• D. $108$

Answer 1

The correct option is A $96$

Given : Kiran scored $80$ marks in his science test which is $\frac{5}{6}$ of total marks

Let the total marks be $x$

Then $\frac{5}{6}$ of total marks scored by Kiran in science $=\frac{5}{6}\times x=\frac{5x}{6}$

But Kiran scored $80$ marks

$\therefore \frac{5x}{6}=80$

Multiplying by $6$ on both the sides, we get

$\frac{5x}{6}\times 6=80\times 6$

$5x=480$

Dividing by $5$ on both sides, we get

$\frac{5x}{5}=\frac{480}{5}$

$\Rightarrow x=96$

Thus, the total marks is $96$.
