remaining amount, he spent 40% on bills, 30% on groceries, 10% on transportation, and saved Rs. 1800. Find the amount spent by him on groceries.Solution
ATQ,
Let the monthly income of Rajesh be Rs. 100x
So, 0.85 × 100x × 0.30 = 1800
Or, 25.5x = 1800
Or, x = 70.59
Desired amount = 0.30 × 85x = 0.30 × 85 × 70.59 = Rs. 1800
