a) 567
b) 576
c) 675
d) 657
correct answer is: d) 657
Explanation
The product of two number is  55188 .
Here,  42  is half of one number.
 \therefore  One number is  =\left(42\times2\right) 
 \rightarrow 84 
Let, Other number be  ‘x’ 
According to the question,
 \left(x\times84\right)=55188 
 \rightarrow x=\large\frac{55188}{84}  [interchange]
 \therefore x=657 
 \therefore  Other number is  657 .
Ans: The other number is 657.
