Q. A man bought a bicycle for $120 and sold it for $150. What is the profit percentage?
Q. A person has a total of $5000 in two accounts. If the first account earns 4% interest and the second earns 6%, how much is in the first account if the total interest earned in one year is $240?
A.
$2000
B.
$3000
C.
$2500
D.
$1500
Solution
Let the amount in the first account be x. Then, amount in the second account = 5000 - x. Interest from first account = 0.04x, from second = 0.06(5000 - x). Total interest = 0.04x + 0.06(5000 - x) = 240. Solving gives x = $2500.
