Solution

The first step is to find out how much Jacob spent on "others". We know that 15% of his expenditure on "others" is 450.So,wecansetuptheequation0.15x=450,wherexistheamounthespenton"others".Solvingforxgivesusx=450. So, we can set up the equation 0.15x = 450, where x is the amount he spent on "others". Solving for x gives us x = 450 / 0.15 = $3000.

Next, we need to find out how much Jacob spent on food. The problem doesn't give us a direct percentage or amount that Jacob spent on food out of his expenditure on "others". Therefore, we cannot find the exact amount Jacob spent on food from the information given in the first question. None of the options A, B, C, D can be confirmed as the correct answer.

For the second question, we know that Jacob spent 360moreonfoodandtransporttogetherthanhespenton"others".Sincewevealreadyfoundoutthathespent360 more on food and transport together than he spent on "others". Since we've already found out that he spent 3000 on "others", this means he spent 3000+3000 + 360 = $3360 on food and transport together.

Finally, to find his total monthly expenses, we add up his expenditure on "others" and his expenditure on food and transport. This gives us 3000(others)+3000 (others) + 3360 (food and transport) = $6360. Therefore, none of the options A, B, C, D are correct for the second question either.
