There are four persons A, B,C and D, and the ratio of the present age...
Given Information:
- There are four persons A, B, C, and D.
- The ratio of the present age of A to C is 4:3.
- C is 7 years younger than E.
- E is 16 years old at present.
- The present age of B is 75% of the present age of D.
- B is 6 years older than A.
To Find:
- The average present age of persons B, C, and D.
Solution:
Let's solve the problem step by step:
Step 1: Find the present age of A and C.
Given that the ratio of the present age of A to C is 4:3.
Let the age of A be 4A.
So, the age of C is 3A.
Step 2: Find the present age of E.
Given that C is 7 years younger than E, and E is 16 years old at present.
So, the present age of C is (16 - 7) = 9 years.
Step 3: Find the present age of B.
Given that B is 6 years older than A.
So, the present age of B is (4A + 6) years.
Step 4: Find the present age of D.
Given that the present age of B is 75% of the present age of D.
So, (4A + 6) = (75/100) * D.
Simplifying this equation, we get D = (18/25) * (4A + 6).
Step 5: Find the present age of C in terms of A.
Given that the ratio of the present age of A to C is 4:3.
So, (4A/3A) = (12/9).
Simplifying this equation, we get C = 3A.
Step 6: Substitute the values of A and C in terms of A.
We know that C = 3A and A = 4A.
So, C = 3(4A) = 12A.
Step 7: Substitute the value of A in the equation for the present age of B.
We know that B = 4A + 6.
So, B = 4(4) + 6 = 22.
Step 8: Substitute the value of A in the equation for the present age of D.
We know that D = (18/25) * (4A + 6).
So, D = (18/25) * (4(4) + 6) = 24.
Step 9: Calculate the average present age of B, C, and D.
The average present age of B, C, and D = (22 + 12 + 24)/3 = 58/3 = 19.33 years.
Therefore, the average present age of persons B, C, and D is approximately 19.33 years.
Correct Answer: Option C (EBADC)
- There are four persons A, B, C, and D.
- The ratio of the present age of A to C is 4:3.
- C is 7 years younger than E.
- E is 16 years old at present.
- The present age of B is 75% of the present age of D.
- B is 6 years older than A.
To Find:
- The average present age of persons B, C, and D.
Solution:
Let's solve the problem step by step:
Step 1: Find the present age of A and C.
Given that the ratio of the present age of A to C is 4:3.
Let the age of A be 4A.
So, the age of C is 3A.
Step 2: Find the present age of E.
Given that C is 7 years younger than E, and E is 16 years old at present.
So, the present age of C is (16 - 7) = 9 years.
Step 3: Find the present age of B.
Given that B is 6 years older than A.
So, the present age of B is (4A + 6) years.
Step 4: Find the present age of D.
Given that the present age of B is 75% of the present age of D.
So, (4A + 6) = (75/100) * D.
Simplifying this equation, we get D = (18/25) * (4A + 6).
Step 5: Find the present age of C in terms of A.
Given that the ratio of the present age of A to C is 4:3.
So, (4A/3A) = (12/9).
Simplifying this equation, we get C = 3A.
Step 6: Substitute the values of A and C in terms of A.
We know that C = 3A and A = 4A.
So, C = 3(4A) = 12A.
Step 7: Substitute the value of A in the equation for the present age of B.
We know that B = 4A + 6.
So, B = 4(4) + 6 = 22.
Step 8: Substitute the value of A in the equation for the present age of D.
We know that D = (18/25) * (4A + 6).
So, D = (18/25) * (4(4) + 6) = 24.
Step 9: Calculate the average present age of B, C, and D.
The average present age of B, C, and D = (22 + 12 + 24)/3 = 58/3 = 19.33 years.
Therefore, the average present age of persons B, C, and D is approximately 19.33 years.
