Correct Answer - Option 1 : 800

Concept used:

1 thousand = 1000

1 hundred = 100

1 tens = 10

Calculation:

79 thousand + 19 hundred - 90 tens = (_____) hundred

Let x will come in place of blank space.

⇒ 79 × 1000 + 19 × 100 - 90 × 10 = x × 100

⇒ 79000 + 1900 - 900 = 100x

⇒ 100x = 80900 - 900

⇒ 100x = 80000

⇒ x = 80000/100 = 800

∴ 800 come in place of blank space.
