Any another method to solve it
To find Ruhi's monthly salary, we need to determine the total amount she spends on rent, transportation, and bills.
Let's assume that the total amount Ruhi spends on these three categories is R.
According to the given ratio of 7:5:3, the amount spent on transportation is 5 units out of the total 7+5+3 = 15 units.
We are given that Ruhi spent 3560 on transportation, which is equivalent to 5 units. Knowing this, we can calculate the value of 1 unit by dividing the amount spent on transportation by 5:
Value of 1 unit = 3560 / 5 = 712.
Since the ratio is given in terms of units, each unit corresponds to a certain amount of money.
Now, we can find the total amount Ruhi spends on rent, transportation, and bills combined by multiplying the value of 1 unit by the total number of units (15):
Total amount spent (R) = Value of 1 unit * Total number of units = 712 * 15.
This gives us the total amount Ruhi spends on rent, transportation, and bills.
To find Ruhi's monthly salary, we subtract the total amount spent on expenses from the monthly salary:
Monthly salary = Total amount spent + R.
Therefore, the monthly salary of Ruhi can be calculated as:
Monthly salary = 712 * 15 + R.
