Problema Solution
magnus invested $10,000, part in one fund which yields a 15% profit, and the rest in a fund which yields an 8% profit. Altogether, he earns $1220. How much did he invest in each fund?
Answer provided by our tutors
since
15% of $10,000 profit = 0.15*10000 = $1500 and 1500 > 1220
thus it is impossible for the total profit to be equal to $1220
the problem has no solution.
