Answer 1

HEY Buddy....!! here is ur answer

Answer : 64 kg

Given that : Average weight of 10 students is 42 kg.

Then total weight of students in class = (10×42) = 420 kg

Average is increased by 2 kg when a teacher is included then the number of members will be (10+1) = 11

And now their total weight = (11×44) = 484 kg

Weight of Teacher = (484–420) = 64 kg

So, the weight of Teacher will be 64 kg.

I hope it will be helpful for you...!!
