  • Options
  • A. 34° C
  • B. 35.5° C
  • C. 36° C
  • D. 36.5° C

  • Correct Answer
  • 36° C 

    Explanation

    M + T + W = 3 x 37 = 111° C .....(1)
    T + W + Th = 3 x 34 = 102 ° C ......(ii)
    Let M = y
    Then, Th = 4y/5
    subtraction (ii) from (i) we get,
    M - Th = 9° C
    ? y - 4y / 5 = 9° C
    ? y = 45° C
    ? Temperature on thursday = (4 x 45) / 5° C
    = 36° C
