  • Question
  • In a mens hostel, there were 95 students. To accommodate 30 more students the average is decreased by rupees 5. But total expenditure increased by Rs.500. Find the total expenditure of the hostel now ?


  • Options
  • A. Rs. 4680
  • B. Rs. 4420
  • C. Rs. 4960
  • D. Rs. 5480

  • Correct Answer
  • Rs. 4680 

    Explanation

    Let the expenditure on the 95 students be 'x'

    Then,

    95x + 500 = 120(x ? 5)
    95x + 500 = 120x - 600
    120x - 95x = 1100
    25x = 1100
    => x = 44

    Therefore, total expenditure of the hostel becomes
    95 x 44 + 500 = 4680.
