How can we solve without a calculator? Any mathematical tricks are there? Please tell me.

Search in year.

Big value + small value/2 then,

9700 + 8100/2 = 8900.

How do you take the required average value?

If no. of years 10 means we take 44950 = 4495. So for 5 years we multiple the answer by 2 i.e. 4495*2 = 8990.
