Solution

The correct option is B 57 Kg
According to Noora, her weight (w) is → 55 < w < 62
According to her friend, Noora’s weight (w) is → 50 < w < 60
According to her mother, Noora’s weight (w) is → w
58 (she said not greater than 58, so, the weight can be equal to 58)
Possible weights are → 56, 57, and 58.
Average of possible weights =
$\frac{56 + 57 + 58}{3} = 57 Kg$
