Question

If the sum of two numbers is 24 and the difference between them is 10, Then what is the value of two times the product of the numbers?

A.

328

B.

239

C.

238

D.

832

Correct option is C

Given:

Sum of two numbers = 24

Difference between the two numbers = 10

Solution:

Let the two numbers be x and y, where:

x + y = 24  …(i)

x - y = 10  ….(ii)

Add the equations (i) and (ii):

(x + y) + (x - y) = 24 + 10

2x = 34

x = 17

Substitute x = 17 into equation (i):

x + y = 24

17 + y = 24

y = 7

Now, we have x = 17 and y = 7.

Then,

2xy = 2×17×72\times17×7 = 238​
