Answer:
Rs 10,800
Step-by-step explanation:
Let S be Tutu's salary.
Given:
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.
