Correct option is A
Given:
House Rent = 12% of monthly salary
Conveyance = ₹407
Grocery = ₹8,657
Savings = ₹924
Formula Used:
Salary - (House Rent + Conveyance + Grocery) = Savings
Let salary be x. Then:
x - (0.12x + 407 + 8657) = 924
Solution:
x - 0.12x - 9064 = 924
0.88x = 9988
Monthly Salary = ₹11350.0
