  • B. 281/8%
  • C. 271/8%
  • D. 251/7%

  • Correct Answer
  • 281/8% 

    Explanation

    Let expenses on wheat be 12N.
    Expenses on meat = 17N.
    Expenses on vegetables = 3N.
    ? Total expenses = 32N.

    Increased expenses = ? (120% of 12N) + (130% of 17N) + (150% of 3N)]
    = ? [(120/100) x 12N] + [(130/100) x 17N] + [(150/100) x 3N]
    = ? [72N/5 + 221N/10 + 9N/2]
    = ? (144N + 221N + 45N)/10
    = ? 410N/10
    = ? 41

    ? Total increase percentage = (9N/32N) x 100 %
    = 225/8 %
    = 281/8%
