In a division sum, the dividend is 398, quotient is 15 and the remainder is 8. What is the divisor?

1. 31

2. 26

3. 17

4. 23

Given:

Dividend = 398

Quotient = 15

Remainder = 8

By formula; Dividend = Divisor x Quotient + Remainder

Substitute the values into the formula:

⇒ 398 = Divisor x 15 + 8

⇒ Divisor x 15 = 398 - 8

⇒ Divisor x 15 = 390

⇒ Divisor = $\dfrac{390}{15}$

⇒ Divisor = 26

Hence, option 2 is the correct option.
