Question

19. The sum of two numbers is 30 and their product is 216. What is the value of the
smaller number in those two numbers?​

Answer 1

Answer:

Let the first number be x &

another be 2x

Now,

x+2x=30

3x=30

x=30/3

x=10

So,

first number is 10 &

second number is 2x

=2*10

=20

Answer 2

Step-by-step explanation:

• let us consider the two numbers x and y
• from given
• x+y=30,x=30-y
• xy=216
• (30-y)(y)=216
• 30y-y^2=216
• y^2-30y+216=0

by factorise

• y^2-18y-12y+216=0
• y(y-18)-12(y-18)=0
• y=18and 12
• if y=18 ,x=12
• smaller number x=12
