Question

If a man spends 1000rs for the first five months, 2000rs for the next four months and 3000rs for the next 3 months and he saves 2000rs in the whole year then his average monthly salary will be ?

Answer 1

$\Rightarrow$ Total money man earned in one year $=(5\times Rs.1000)+(4\times Rs.2000)+(3\times Rs.3000)+Rs.2000$

$=Rs.5000+Rs.8000+Rs.9000+Rs.2000$

$=Rs.24000$

$\Rightarrow$ Average monthly salary $=\frac{Rs.24000}{12}=Rs.2000$
