Answer 1

$\large\bf Given:-$

• Arshi earns Rs. 30000 per month.

• He spends ¼ of his income on food.

• He spent 3/10 of his remaining income on his house rent.

• He spent 5/21 of his remaining income on his children's education.

$\large\bf To\:Find:-$

• The money still left with him.

$\large \bf Solution:-$

Total income of Arshi = Rs.30000

---»¼ of his income is spent in food

$\rm \implies \dfrac{1}{4} \times 30000$

$\rm \implies Rs.7500$

Remaining money = 30000 - 7500
= Rs. 22500

---»3/10 of the remaining income is spent on house rent

$\rm \implies \dfrac{3}{10} \times 22500$

$\rm \implies Rs. 6750$

Remaining money = 22500 - 6750
= Rs. 15750

---»5/21 of the remaining income is spent on his children's education

$\rm \implies \dfrac{5}{21} \times 15750$

$\rm \implies 5 \times 750$

$\rm \implies Rs. 3750$

Remaining money = 15750 - 3750
= Rs. 12000

$\large\underline{\boxed{\rm \purple{Remaining\: money = Rs.12000}}}$
