the ratio of two numbers is 2:3 when 4 is added to both the numbers the ratio become 3:4, what is the sum of numbers
Answers
Answer:
Let their common ratio is x
then numbers will be 2x and 3x
when 9 is added to each they become (2x+9)and (3x+9)
so their ratio
(2x+9)/(3x+9)=3/4
8x+36=9x++27
x=36–27
x=9 so the original numbers will be
2x=2*9=18 and 3x=3*9=27
so their product will be
18*27=486
Step-by-step explanation:
Given:
The ratio of the two numbers = 2: 3
New ratio, after addition of 4 to both the numbers = 3: 4
To find:
The value so obtained after adding the two numbers.
Solution:
Let us represent the numbers by X.
The ratio of the numbers = 2 X: 3 X
The sum of the two numbers = 2 X + 3 X
After adding 4 to the two numbers, the new ratio becomes 3: 4.
Therefore,
=
After solving the above equation, we can get the value of X.
X= 4
The two numbers are;
2 X =(2 × 4 ) = 8
3 X = (3 × 4 )= 12
On adding the two numbers,
= 2 X + 3 X
= 8 + 12 = 20
Therefore, the sum of the numbers 8 and 12 is 20.
