rent, respectively. Of the remaining amount, he gave 20% and 40% to his mother and brother, respectively. Find the amount spent by him on food, if the difference between the amount received by his brother and the amount spent on rent is Rs. 1440.Solution
Let the monthly salary of A be Rs. βxβ Amount spent on food = Rs. 0.33x Amount spent on rent = Rs. 0.22x Amount received by brother = (x - 0.33x - 0.22x) x 0.40 = 0.18x So according to question: 0.22x - 0.18x = 1440 0.04x = 1440 x = 36000 So, the amount spent on food = 0.33 x 36000 = Rs. 11880
