Neha spends 60% of her monthly income. If her monthly
income increased by 35% and her expenditure remained the same, then she would be able to save Rs. 10,000 every month. Find the monthly expenditure of Neha.Solution
ATQ, Let the monthly income of Neha be Rs. '100u' Her monthly expenditure = 100u × 0.60 = Rs. '60u' Her monthly savings = 100u - 60u = Rs. '40u' New income of Neha = 100u × 1.35 = Rs. '135u' New savings of Neha = 135u - 60u = Rs. '75u' ATQ; 75u = 10000 So, u = 133.33 So, Neha's monthly expenditure = 60u = 133.33 × 60 = Rs. 8,000
