Show answer & explanation
Correct answer: C
To find the number of students whose pocket allowances are less than ₹ 40, we need to analyze the provided histogram.
Step-by-Step Solution
Identify the relevant bars: The x-axis represents "Pocket Expenses (in ₹)" and the y-axis represents the "No. of Students". We are looking for students whose pocket allowance is less than ₹ 40.
Read the histogram:
The first bar covers the range from ₹ 0 to ₹ 20. The height of this bar is 20.
The second bar covers the range from ₹ 20 to ₹ 40. The height of this bar is 10.
Sum the students: Since we need the total number of students with an allowance less than ₹ 40, we add the counts from both bars:
20 (students in 0–20 range) + 10 (students in 20–40 range) = 30 students.
