A) 100000
B) 39684
C) 69842
D) 30158
Correct Answer: A
Solution :
\[\frac{69842\times 69842-30158\times 30158}{69842-30158}\] \[=\frac{{{(69842)}^{2}}-{{(30158)}^{2}}}{(69842-30158)}\] \[=\frac{(69842+30158)\,\,(69842-30158)}{(69842-30158)}\] \[=(69842+30158)\] \[=100000\]You need to login to perform this action.
