Question
Mohan allocates 40% of his monthly income for rent.
After paying for rent, he uses 30% of the remaining amount for groceries. Additionally, he spends an amount equal to 25% of his rent expense on his gym membership. From the leftover money, he spends Rs. 5,200 on miscellaneous items and saves the remaining amount. The difference between his savings and the rent expense is Rs. 10,000. Can you determine Mohan's total monthly income?Solution
Let the monthly income of Mohan be Rs. '100x' So, rent expense of Mohan = 100x X 0.4 = Rs. '40x' Amount spent on groceries = (100x - 40x) X 0.3 = Rs. '18x' Amount spent on Gym = 40x X 0.25 = Rs. '10x' Amount saved = 100x - 40x - 18x - 10x - 5200 = Rs. (32x - 5200) ATQ; 40x - 32x + 5200 = 10000 Or, 8x = 4800 So, x = 600 So, income of Mohan = 600 X 100 = Rs. 60,000
