Ratio between present ages of A, B and C is 5:4:6. Total of the ages o...
Option (2) 5:7 is correct✅answer.
Explanation:-
Let age of A = 5 x
B= 4x
C = 6x
Then, according to the question;
( 5x+5) + (6x+5) = 54
11x + 10 = 54
=> 11x = 54-10
=> 11x = 44
=> x = 4
B's age after 4 years;
= 4x +4
=> 4*4+4
=> 20 years.
C's age after 4 years ;
= 6x+4
=>6*4+4
= 28 years
Therefore, ratio = 20/28
=> ratio = 5:7

Given information:
- The ratio between the present ages of A, B, and C is 5:4:6.
- The total of the ages of A and C after 5 years will be 54 years.
Let's assume the present ages of A, B, and C to be 5x, 4x, and 6x respectively.
Age of A after 5 years = 5x + 5
Age of C after 5 years = 6x + 5
According to the given information, the total of the ages of A and C after 5 years will be 54 years.
So, we have the equation:
(5x + 5) + (6x + 5) = 54
11x + 10 = 54
11x = 44
x = 4
Therefore, the present ages of A, B, and C are 20, 16, and 24 respectively.
Now, we need to find the ratio of the ages of B and C after 4 years.
Age of B after 4 years = 16 + 4 = 20
Age of C after 4 years = 24 + 4 = 28
So, the ratio of the ages of B and C after 4 years is 20:28, which can be simplified to 5:7.
Therefore, the correct answer is option B) 5:7.
