Question

If no two children can work simultaneously so that each task is done one after the other, then what will be the least amount a parent has to give to all the tasks done?

• A. $\$150$
• B. $\$147$
• C. $\$143$
• D. $Cannotbedetermined$

Answer 1

The correct option is C $\$143$

For this we need to minimize the cost for each of the task, then we will find the minimum cost.
Minimum cost $=\$23$ (Child 4 going for Morning walk) + $\$37$ (Child 5 doing Exercise) $+\$28$ (Child 1 doing home work) $+\$21$ (Child 2 drink Milk) $+\$34$ (Child 3 family work)$=\$143$
