Question

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

• A. 3:1
• B. 3:4
• C. 1:3
• D. 4:3

Answer 1

The correct option is B 3:4

Given: Marks obtained by Mala = 75 marks
Marks obtained by Bala = 25 marks
Total marks scored by both = 75 + 25 = 100 marks
$\Rightarrow$ Ratio of marks scored by Mala to the total marks obtained
= $\frac{MarksscoredbyMala}{Totalnumberofmarksscoredbyboth}$
= $\frac{75}{100}$
= $\frac{3}{4}$ i.e. 3:4
Therefore, the required ratio is 3:4.
