    Solution

    Let the monthly salary of A be Rs. ‘x’ Amount spent on food = Rs. 0.37x Amount spent on rent = Rs. 0.25x Amount received by brother = (x - 0.37x - 0.25x) x 0.40 = 0.152x So according to question: 0.25x - 0.152x = 2940 0.098x = 2940 x = 30000 So, the amount spent on food = 0.37 x 30000 = Rs. 11100
