Question

Kelly invested $1,500 in the stock market on January 1st. She lost 1/3 of it by the end of January and 2/5 of the remaining amount by the end of February. How much did she have left?

Answer 1

by the end of January, Kelly lost (1/3) of 1500 = $500

at the beginning of February, Kelly has 1500- 500 = $1000 left

Then in mid-February, she lost another (2/5) of 1000 = $400

Kelly has 1000 - 400 = $600 left
