Answer:
Correct Answer: A
Solution:
- Here, let the one even number be $ x. $ Then, another even number is $ (x+2). $ Now, $ x(x+2)=3248 $ or $ x^{2}+2x-3248=0 $
$ \Rightarrow $ $ x^{2}+58x-56x-3248=0 $ [by splitting the middle term]
$ \Rightarrow $ $ x(x-56)+58(x-56)=0 $
$ \Rightarrow $ $ (x+58)(x-56)=0 $
$ \Rightarrow $ $ x=56 $
$ \therefore $ Larger number $ =x+2 $
$ \Rightarrow $ $ 56+2=58 $
