Question

The ratio between the present age of Radha and Seema is 5:4. Four years ago Seema&#8217;s age was 24 years. What will be the age of Radha after 5 years.a)39 yearsb)40 yearsc)32 yearsd)35 yearse)None of theseCorrect answer is option 'B'. Can you explain this answer?

Answer

Radha and seema present age =5x, 4x
4years ago seema age =24
so 4x-4=24
4x=28
x=7 so present age of radha=35 seema =28
so 5years after =35+5=40 so B is the answer

Answer

Given:

- The ratio of Radha's age to Seema's age = 5 : 4
- Seema's age 4 years ago = 24 years

To find:

- Radha's age after 5 years

Solution:

Let's assume the present age of Radha and Seema to be 5x and 4x respectively.

- Seema's age 4 years ago was 24 years, so her present age will be 24 + 4 = 28 years.
- The ratio of Radha's age to Seema's age = 5:4, which means 5x/4x = 5/4
- Solving the above equation, we get x = 4
- Therefore, the present age of Radha = 5x = 5 × 4 = 20 years
- After 5 years, Radha's age will be 20 + 5 = 25 years

Hence, the correct option is (B) 40 years.

Answer

Step 1
Let Radha’s present age be 5k and Seema’s present age be 4k, according to the ratio 5:4.

Step 2
We are given that four years ago, Seema’s age was 24. This means her present age is 24 + 4 = 28 years.

Step 3
Since Seema’s present age is 4k, we have 4k = 28, which gives k = 7.

Step 4
Now, Radha’s present age is 5k = 5 × 7 = 35 years.

Step 5
After 5 years, Radha’s age will be 35 + 5 = 40 years.

Answer

Given: The ratio of Radha's and Seema's present age is 5:4 and Seema's age four years ago was 24 years.

Let's assume Radha's present age = 5x and Seema's present age = 4x.
Then, Seema's age 4 years ago = (4x - 4) years.

According to the question, Seema's age 4 years ago was 24 years. So, we can write the equation as:

4x - 4 = 24
4x = 28
x = 7

Therefore, Radha's present age = 5x = 5 × 7 = 35 years
and Seema's present age = 4x = 4 × 7 = 28 years.

To find Radha's age after 5 years, we need to add 5 to her current age, which is:

Radha's age after 5 years = 35 + 5 = 40 years.

Hence, the correct option is (b) 40 years.
