At the end of 2014, several states in Malaysia were hit by severe floods. The table below shows an estimated number of flood victims in three states.

Calculate the total number of flood victims in the three states. 

SOLUTION:

Terengganu:
45 400 - 10 800 = 34 600 people
\(\begin {array}{rr} \\ \space\space 4\space5\,\space\space4\space0\space0\\ - \quad\space1\space0\,\space\space8\space0\space0 \\\hline\space\space3\space4\,\space\space6\space0\space0\\\hline \end {array} \)

Total number of flood victims in the three states:
45 400 + 34 600 + 33 000 = 113 000
\(\begin {array}{rr} \\ \space\space\small{\color{red}1}\space \small{\color{red}1}\space\space\space\space\space\quad\quad \\ \space 4\space5\,\space\space4\space0\space0\\ \quad\space3\space4\,\space\space6\space0\space0\\ + \quad\space3\space3\,\space\space0\space0\space0 \\\hline1\space\space1\space3\,\space\space0\space0\space0\\\hline \end {array} \)

In 2015, a factory produced \(\frac{1}{5}\) million kilogram of cooking oil for export. Production targets in each subsequent year is 2 times the mass of cooking oil compared to the previous year. What is the mass, in kg, of cooking oil produced in 2019?

SOLUTION:

\(\frac{1}{5}\times1\ 000\ 000=200\ 000\)

Mass of cooking oil produced in 2019 is 3 200 000 kg.
