Answer:

Simran's weight = 35 kg

Step-by-step explanation:

Average weight of the four children = 35 kg

Average formula = sum of values/no. of values

let simran's weight be x kg

A.T.Q. - (Ajay's weight + Ranu's weight + manav's weight + simran's weight)/4 = 35 kg

(107 + x)/4 = 35

107 + x = 35 × 4

107 + x = 140

x = 140 - 107

x = 33

Simran's weight = 33 kg
