Word Problems - The sum of two numbers is 6 78 90 581. If one of them is 3 42 16 789,find the other number. also find which of the two numbers is greater​

Answer 1

Answer:

Solution :

Let the First number = x

and the Second number = y

According to the condition,

x=y+15\ \ \dots(i)x=y+15 …(i)

x+y=195\ \ \ \ \dots(ii)x+y=195 …(ii)

Substituting the eq. (i) in eq. (ii), we will get,

x+y=195x+y=195

\Rightarrow y+15+y=195⇒y+15+y=195

⇒2y=195-15⇒2y=195−15

⇒y=\frac{180}{2}⇒y=

2

180

⇒y=90⇒y=90

Now substituting the value of y in eq. (i), we will get

x=y+15x=y+15

\Rightarrow90+15=105⇒90+15=105

∴ The two numbers are 105 and 90.
