Video Summary

The problem involves calculating Lucy and her mother's combined birth years and ages as of March 19, 2015. Lucy was born in February of an unknown year, and on March 19, 2015, her age plus her birth year equals 2015. Similarly, her mother's age plus birth year also equals 2015. The key is that both combinations yield 2015, so their combined sum (adding both their ages and birth years) is doubled: 2015 + 2015 = 4030. Therefore, the result Lucy obtains is 4030.
