Solution

Expenditure of A on food= 28000*0.25=Rs. 7000 Remaining income = 28000-7000=Rs. 21000 Expenditure of A on medicine = 21000*0.4 = Rs. 8400 So amount saved by A = 28000-(7000+8400) = Rs. 1260 Savings of B= 12600+600 = Rs.13200 Income of B = 28000*1.15=Rs. 32,200 So total expenditure of B = 32200-13200 = 19000 So expenditure of B on medicine = 19000*0.3 = Rs. 5700 Quantity 2 Number of boys in the class = 8750*0.44 = 3850 Number of girls in the class = 8750-3850 = 4900 Number of boys who wrote the examination= 3850*0.6 = 2310 The number of girls who wrote examination = 4900*0.45 = 2205 Number of boys who passed the examination = 2310-160 = 2150 Number of girls who passed the examination = 2205-155 = 2050 So total number of student who pass examination.= 2150+2050 = 4200
