If 54 is dividend, 6 is divisor and 9 is quotient then divisor into dividend will be equal to which of the following?  

The correct option is (C).

Given- 54 is dividend 

6 is divisor

9 is quotient

Then, 

Divisor $\times$quotient  = $6\times 9=54$

Therefore,  if 54 is dividend, 6 is divisor and 9 is quotient then divisor into dividend will be equal to dividend that is 54.
