Find the average weight of four containers, if it is known that the weight of the first container is 100 kg and the total of the second, third and fourth containers’ weight is defined by f(x) = x2 – 3/4 (x2), where x = 100.
1. 650 kg
2. 880 kg
3. 760 kg
4. 460 kg

Ans:650kgs
weight of 2nd,3rd and 4th cylinders are calculated by the function f(x)
then we will get it as 2500
and it is also given that 1st cylinder weight is 100.
so add 2500 and 100 which gives weight of 4 cylinders=2600
then average is 2600/4=650kg.
