Raju & Akshara Weight = 62 kg , Rakesh Weight = 59 kg if Mean Weight = 61 kg , Rakesh weight is 3 kg less than Raju and Raju , akshara have same weight
Step-by-step explanation:
Let say Raju Weight = W kg
Raju & akshar a have Same Weight
=> Akshara Weight = W kg
Rakesh Weight is Less than 3 kg of Raju Weight'
=> Rakesh Weight = W - 3 kg
Total Weight of Raju , Akshara & Rakesh = W + W + W - 3
= 3W - 3
= 3(W - 1) kg
Mean Weight of three STudents = 3(W - 1)/3 = W - 1 kg
W - 1 = 61
=> W = 62
Raju & Akshara Weight = 62 kg
Rakesh Weight = 62 - 3 = 59 kg
