A man can row 12 km downstream and 8 km upstream in 4 hours. He can also row 16 km downstream and 12 km upstream in 6 hours. Find the speed of the man in still water and the speed of the current.

Let the speed of the man in still water be x km/hr and the speed of the current be y km/hr. Set up two equations based on the given data: 12/(x + y) + 8/(x – y) = 4 and 16/(x + y) + 12/(x – y) = 6. Solving these equations simultaneously gives x = 7 km/hr and y = 3 km/hr.

A man invested ₹20,000 in two different schemes for one year. He invested part of the amount at 10% per annum and the remaining at 20% per annum. If he received a total interest of ₹3,000 at the end of the year, how much did he invest at 10%?

Let the amount invested at 10% be ₹x. Then, amount invested at 20% is ₹20,000 – x. Total interest for one year is ₹3,000 = 10% of x + 20% of (₹20,000 – x). Solving this equation gives x = ₹10,000.
