`<b><i>HEY THERE !!`

As you are saying that a country's population was 340,000 in 1980 AD .

And it increased 20% in the decade of 1980 - 1990 .

So now we have to find 20% of 340,000

=> (340,000/ 100) × 20
=> 68000

So now the country's population in 1990 AD was = 340,000 + 68000
=>
`\boxed{408000. }`

HOPE IT HELPED YOU.

340,000 + 68,000 = 408,000

The Country's population was
`\boxed{ \bf 408,000}` in 1990.
