A father said to his son, "I was as old as you are at the present at the time of your birth". If the father's age is 55 years now, what would be the son's age 4.5 years later?
Let the sons current age be x
So fathers age x years back when son was born => 55-x = x
Solving we get x = 27.5
4.5 Years later son's age = 27.5 + 4.5 = 32 years

A merchant has 1925 kg of sugar, part of which he sells at 3% loss and the rest at 4% profit. He gains 2% on the whole. What is the difference between the quantities of sugar sold at 4% profit and that sold at 3% loss?
(Quantity of Cheaper)/(Quantity of Dearer) = (Price of Dearer - Mean Price)/(Mean Price - Price of Cheaper)
(Quantity of Cheaper)/(Quantity of Dearer) = (104 - 102)/(102-97) = 2/5
Total Quantity = 1925 KG
The quantity sold at 3% loss is = (2/7) * 1925 = 550 Kgs
The quantity sold at 4% profit is = (5/7) * 1925 = 1375 Kgs
Difference between Quantity = 1375 - 550 = 825 Kgs
