The ratio between two numbers is 3 : 4. If each number is increased by...
Let the number are 3x and 4x.
3x+64 / 4x+65 = 4/5
15x + 30 = 16 x + 24
x = 6
Number are 18 and 24.
Hence, required difference is 6.

The ratio between two numbers is 3 : 4. If each number is increased by...
Sol:- Given x:y = 3:4. =>x/y=3/4;
x=3y/4. =>. eq(1);
and (x+6)/(y+6) = 4/5 =>. eq(2)
substitute eq(1) in eq(2);
then we get y=24 and x =18;
Finally difference between two numbers is 24-18 =6;
The ratio between two numbers is 3 : 4. If each number is increased by...
Given information:
The ratio between two numbers is 3:4.
If each number is increased by 6, the ratio becomes 4:5.
Let's assume the two numbers to be 3x and 4x, where x is a common factor between them.
Finding the ratio before the increase:
The ratio of the two numbers is given as 3:4.
Therefore, we can write the equation as:
3x : 4x
Finding the ratio after the increase:
If each number is increased by 6, the new numbers will be:
3x + 6 and 4x + 6
The ratio of the new numbers is given as 4:5.
Therefore, we can write the equation as:
(3x + 6) : (4x + 6)
Equating the ratios:
We can equate the two ratios to find the value of x.
(3x + 6) : (4x + 6) = 4 : 5
Cross-multiplying:
5(3x + 6) = 4(4x + 6)
15x + 30 = 16x + 24
Simplifying the equation:
Bringing like terms together:
15x - 16x = 24 - 30
-x = -6
Dividing by -1:
x = 6
Finding the numbers:
Using the value of x, we can find the numbers:
First number = 3x = 3(6) = 18
Second number = 4x = 4(6) = 24
Finding the difference between the numbers:
Difference = Second number - First number = 24 - 18 = 6
Therefore, the difference between the numbers is 6. Hence, the correct answer is option 'C'.
