C) 42 |

D) 54 |

Correct Answer:

D) 54 |

Description for Correct answer:

Let the number be x and y.

Then, according to the question,

x + y = 15 ...(i)

x - y = 3 ...(ii)

On adding Eqs. (i) and (ii), we get

2x =18 = x = 9

On putting the value of x in Eq. (i), we get

y = 6

Therefore, Product = xy = 9 x 6 = 54
