How you made every concept so easy for us is just amazing! Thank you sir
[ Home Work 1 answer is 145 ] To verify I also checked answer on the internet. So people who are saying 25 are wrong. First you do 12*5=60. Now this is where everyone gets wrong answers: You have to do 90+60=150 not "minus" because the original average should have been greater, that's why it reduced. Now 150-5=145

2examples were different : in 34.14 the math was about decreased average ( from 15 to average became 14.8, so the rate of decrease is 0.2 which was multiplied with 20) and in 21.44 the math was about how much decreased ( 12 divided by 6 which came out with the decreased rate,there 16 was the new item not the average) I hope you get this! sorry if I could not able to make you understand.
The average of 5 number is 7 when 3 new numbers are added the average of the eight number is 8.5 the average of 3 new number is!! Please solve this
