Question
A person sells each package of snacks for Rs. 12 each.
On Monday, he sold 120 packages which was 30 more than that on Tuesday but 25 less than that on Wednesday. If he spends 70% of his income earned by selling snack packages on these 3 days, then find his saving in given 3 daysSolution
Number of packages of snack sold on Monday = 120 Number of packages of snack sold on Tuesday = 120 – 30 = 70 Number of packages of snack sold on Wednesday = 120 + 25 = 145 Therefore, his total income of 3 days = (120 + 90 + 145) × 12 = 355 × 12 = Rs. 4260 Therefore, savings of person in given 3 days = 0.3 × 4260 = Rs. 684
