Tutu pays 60% of his salary on rent, 15% of his salary on loan installment and still saves Rs 900 after spending Rs 1800 on other household goods. What is his salary in Rs?



Answer :

Answer:

Rs 10,800

Step-by-step explanation:

Let S be Tutu's salary.

Given:

  • 60% of his salary is spent on rent = 0.6S
  • 15% of his salary is spent on loan instalments = 0.15S
  • Rs 1800 is spent on other household goods = 1800
  • He saves Rs 900 after all expenses = 900

Therefore, Tutu's total salary is the sum of his expenses and savings:

[tex]\sf S = 0.6S + 0.15S + 1800 + 900[/tex]

Simplify the equation and solve for S:

[tex]\sf S = 0.75S + 2700\\\\S - 0.75S = 2700\\\\0.25S = 2700\\\\S=\dfrac{2700}{0.25}\\\\S=10800[/tex]

Therefore, Tutu's salary is Rs 10,800.
