Question

Mala and Bala got $75$ marks and $25$ marks respectively in an examination. The ratio of the marks scored by Mala to the total marks obtained by both of them is

• A. $3:4$
• B. $3:1$
• C. $1:3$
• D. $4:3$

Answer 1

The correct option is A $3:4$

Let $x$ and $y$ denote the marks obtained by Mala and Bala

$\therefore x=75$ and $y=25$

Now, total marks $=x+y=75+25=100$
$\therefore$ Ratio of Mala's marks to that of total marks $=x:\text{total marks}=75:100=3:4$

Hence, option A is correct.
