Question
In a boat, 25 persons were sitting. Their average weight increased by one kilogram when one man leaves and a new man comes in. The weight of the new man is 70 kgs. Find the Weight of the man who has left.
Solution
Step 1: Understand the problem. The average weight of 25 people increased by 1 kg when one person left and a new person came in. The new person weighs 70 kg. We need to find the weight of the person who left.
Step 2: Set up the equation. The total weight of the 25 people increased by 1 kg, so the total increase in weight is 25 kg (1 kg per person).
Step 3: Solve the equation. The new person weighs 70 kg, so the person who left must have weighed 70 kg - 25 kg = 45 kg.
So, the weight of the man who left the boat is 45 kg.
