If the sum of two numbers is 14 and their diffenrece is 10. Find the product of these two numbers.
(a) 18
(b) 20
(c) 24
(d) 22
Answer: (c) 24
Explanation:-
Let the two numbers be X and Y.
The sum of two numbers is 14.
Then, X + Y = 14 …………….. (1)
And their difference is 10.
Then, X – Y = 10 ………….. (2)
Add equation (1) & (2).
Then, X + Y + X – Y = 14 + 10
2 X = 24
X = 24/2
X = 12
Then, Y = 14 – 12
= 2
So, the product of these to numbers = 12 x 2
= 24.
Hence, the correct answer is option (c) 24.
