A) 11
B) 13
C) 17
D) 19
Correct Answer: D
Solution :
Let the number be a, b, c and d Given that \[a\times b\times c=2,431\] .............(i) and \[b\times c\times d=4,199\] .............(ii) Now, divide equation (ii) by equation (i) \[\frac{b\times c\times d}{a\times b\times c}=\frac{4,199}{2431}\]\[\Rightarrow \frac{d}{a}=\frac{4,199}{2431}=\frac{13\times 17\times 19}{11\times 13\times 17}=\frac{d}{a}=\frac{19}{11}\] Hence, the largest number is 19.You need to login to perform this action.
