Correct Answer: 135 kg
Solution : Given, the average weight of 5 men decreases by 3 kg when one of them weighing 150 kg is replaced by another person. When the average weight of 5 men decreases by 3 kg, the total sum of weight should reduce by 5 × 3 kg = 15 kg So, the new weight should be 15 kg less than 150 kg. ⇒ New weight = 150 kg – 15 kg = 135 kg Hence, the correct answer is 135 kg.
