A factory produces certain number of items out of which ratio of sold to unsold items is 7 : 3. If difference between sold to unsold items is 100, then what is the total number of items produced by the factory? Correct Answer 250

GIVEN:

Ratio of sold to unsold items is 7 : 3

Difference between sold to unsold items is 100

7x – 3x = 100

⇒ 4x = 100

⇒ x = 25

∴ Total produced items = 7x + 3x = 10x = 250
