Question

The 10 households on a certain street have household incomes that range from Rs. 34,000 to Rs. 150,000 and an average (arithmetic mean) household income of Rs. 60,000. If the household with the highest income and the one with the lowest income are excluded, what is the average household income for the remaining 8 households?

• A. Rs. 41,000
• B. Rs. 47,000
  
• C. Rs. 52,000
• D. Rs. 61,000

Answer 1

The correct option is C Rs. 52,000

Total income = 60,000 $\times$10 =Rs. 6 lakhs
New Total = 600,000 – (34000 +150000) = Rs. 4,16,000
New Average = $\frac{416000}{8}$ = Rs. 52,000
