Please how can you solve these data interpretations questions quickly without the aid of calculator as I am preparing for an aptitude test in a company that requires no calculator?

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.

Search in year.

Big value + small value/2 then,

9700 + 8100/2 = 8900.
