In 2020 black engineers under 30 is 70% of 500, which is

[tex]\frac{70}{100}\times500=350[/tex]

In 2021 500 members joined making a total of 1000 members.

The black engineers together are now 50% of 1000, which is 500

So the numbers of black engineers that joined in 2021 becomes

[tex]500-350=150[/tex]

Hence the answer is 150
