   1. Explanation:

      Let the Current Total Weight = 45 x 35 = 1575

      by a new Admission, the weight becomes 44.5 so,

      New Total Weight =44.5 x 36 => 1602

      To find the new student age
      = New total Weight – Current Total Weight
      = 1602 – 1575 kg
      = 27 kg
      So the New student age is 27 kg
