Correct Answer - Option 1 : 990

**Given:**

Remainder = 18

Divisor = 12 quotient

And, Divisor = 6 remainder

**Concept Used:**

Dividend = (Divisor) × (Quotient) + Remainder

**Calculation:**

Here, divisor = 6 × 18 = 108

12 Quotient = 108

⇒ Quotient = 108/12 = 9

Now, Dividend = (108) × (9) + 18 = 972 + 18 = 990

**∴ The dividend is 990.**
