The pie-chart shows the domestic budget of a family where: A= Food B = Conveyance C= Clothing D = Miscellaneous Expenses E= Saving F = House Rent If total monthly income of the family is Rs. 30,800, how much amount is spent on house rent ?

The correct answer is B) Rs. 4,620. The pie chart is not reproduced in the question text, so this rests on the options: house rent must be a sector of 15% of the income, which is 54 degrees of the circle.

Check it: 15% of Rs. 30,800 = 30,800 × 15/100 = Rs. 4,620. This is the only option that corresponds to an exact whole percentage of the income. The others are near-miss distractors:

• A) 4,600 is about 14.94%, not a clean sector.
• C) 4,640 is about 15.06%.
• D) 4,650 is about 15.1%.

The core concept is converting a pie-chart sector into a percentage (360 degrees = 100%) and then applying it to the total. This connects to basic data interpretation in Prelims and to household budget analysis in Mains. Before you rely on this, confirm the sector angle on the original chart.

Trap: aspirants pick the option that looks closest to a rough estimate, or they round the angle and land on 4,600 or 4,650 instead of checking for the exact percentage.
