Question

Out of total monthly expenses of our family,

₹ 4750

is spent on food and

₹ 5900

for all other expenses. If expenses on food is increased by

10 %

and other expenses decreased by

16 %

, then let's calculate whether the total monthly expenses will increase or decrease.

Accepted Answer

Monthly expenses of the family spent on food $= ₹ 4750$

Expenses on food is increased by $10 %$ .

So increment in expenses of the family spent on food $= ₹ 4750 \times 10 %$

$= ₹ 4750 \times \frac{10}{100} = ₹ 475$

So new expenses of the family spent on food $= ₹ 4750 + ₹ 475 = ₹ 5225$

Monthly expenses of the family spent on other expenses $= ₹ 5900$

Other expenses decreased by $16 %$ .

So decrement in new expenses of the family spent other than food $= ₹ 5900 \times 16 %$

$= ₹ 5900 \times \frac{16}{100} = ₹ 944$

So decrement in new expenses of the family spent other than food $₹ 5900 - ₹ 944 = ₹ 4956$

Monthly expenses of the family spent on food and other expenses $= ₹ 4750 + ₹ 5900 = 10650$

Monthly expenses of the family spent on food and other expenses after change in their percentage $₹ 5900$

Monthly expenses of the family spent on food and other expenses new $= ₹ 5225 + ₹ 4956 = ₹ 10181$

Difference in the expenses from old to new $= ₹ 10650 - ₹ 10181 = ₹ 469$

Hence, total monthly expenses will decrease by $₹ 469$ .

Out of total monthly expenses of our family, $₹ 4750$ is spent on food and $₹ 5900$ for all other expenses. If expenses on food is increased by $10 %$ and other expenses decreased by $16 %$ , then let's calculate whether the total monthly expenses will increase or decrease.
