and saves Rs. 7000. Rishav, whose monthly income is 20% lower than Ritesh's, spends 75% of his income. Calculate the amount Rishav saves each month.Solution
Let the income of Ritesh be Rs. ‘x’. According to the question, 0.20x = 7000 Or, x = Rs. 35000 Income of Rishav = 0.80 × 35000 = Rs. 28000 Therefore, savings of Rishav = 0.25 × 28000 = Rs. 7000
