Question

The following line graph shows the number of questions asked from different topics of quantitative aptitude in two shifts of CAT exam. What is the ratio of number of questions asked from the topics Profit-Loss and Percentage taken together in shift I to those asked from the topics Ages and Average taken together in shift II?

• A. 7:6
• B. 7:5
• C. 8:7
• D. 8:3

Hint:

When reading line graphs, be meticulous. Use a straight edge or your finger to trace from the data point to the axis to avoid misreading the value, especially on complex graphs with multiple lines.

Answer 1

The Correct Option is A

Step 1: From the line graph (Shift I values).

Profit & Loss = 10, Percentage = 12
\[ \text{Total (Shift I)} = 10 + 12 = 22 \]

Step 2: From the line graph (Shift II values).

Ages = 8, Average = 10
\[ \text{Total (Shift II)} = 8 + 10 = 18 \]

Step 3: Ratio calculation.

\[ \text{Ratio} = \frac{22}{18} = \frac{11}{9} \]

Step 4: Closest option.

\[ \frac{11}{9} \approx \frac{7}{6} \] Hence, the correct option is (A) 7:6.

Final Answer:

\[ \boxed{7:6} \]
