Answer 1

Answer:

• ₹ 3000 was spent on food.
• ₹ 1200 was spent on study.
• ₹ 4200 was spent in total.
• ₹ 7800 was saved in a month.

Step-by-step explanation:

Given that:

• Father earns ₹ 12000 in a month.
• He spends 25% of his income on food.
• He spends 10% of his income on your study.

To find:

• How much money does he spend on food?
• How much money does he spend in your study?
• How much money he spend altogether?
• How much money does he save in a month?​

Solution:

Money spend on food:

$\sf{25\% \;of\; 12000}\\\\= \dfrac{25}{100}\times 12000$

Cutting off the zeros,

$= \sf{\dfrac{25}{1\!\!\!\not{0}\!\!\!\not{0}}\times 120\!\!\!\not{0}\!\!\!\not{0}}\\\\= 25 \times 120$

Multiplying 25 and 120,

= 3000

Hence, father spends ₹ 3000 on food.

Money spend on study,

$\sf{10\% \;of\; 12000}\\\\= \dfrac{10}{100}\times 12000$

Cutting off the zeros,

$= \sf{\dfrac{10}{1\!\!\!\not{0}\!\!\!\not{0}}\times 120\!\!\!\not{0}\!\!\!\not{0}}\\\\= 10 \times 120$

Multiplying 10 and 120,

= 1200

Hence, father spends ₹ 1200 on study.

Money spend in total:

₹(3000 + 1200)

Adding 3000 and 1200,

= ₹ 4200

Hence, ₹ 4200 was spend altogether.

Money saved in a month,

= ₹(12000 - 4200)

Subtracting 4200 from 12000,

= ₹ 7800

Hence, ₹ 7800 was saved in a month.
