Question

the addition of two numbers is 84 first number is more 12 than the second no. find multiplication of the two numbers
(a) 1728 (b) 864 (c) 1656 (d) none of the above

​

Answer 1

Answer:

a)1728

Step-by-step explanation:

The first number is x

The second number is y

So according to the given condition the sum of these two numbers is 84, so we can write

x+y=84 ————-(1)

Again one of them is more than 12 than the other that's why we can write,

x+12=y -------------(2)

Now putting the values of y in equation (1) we get,

x+x+12=84

=>2x+12=84

=>2x+12–12=84–12

=>2x=72

=>2x/2=72/2

=>x=36

Taking the value of x in equation(2) we get,

36+12=y

=>y=48

The two numbers are 48 and 36.

And their product is 1728.
