​

Answer 1

Answer:

Rahim weighs 37 kgs

Step-by-step explanation:

total weight is 120

120 - 46 = 74

74/2 = 37

Answer 2

Answer:

Given average weight of three students is 40Kg

Then total weight of three students=40×3=120Kg

Given weight of one student Ranga is 46kg

Then total weight of Rahim and Reshma =120−46=74Kg

Given weight of Rahim and Reshma is equal

So weight of Rahim= 74/2=37
