Answer 1

Step-by-step explanation:

Ratio of A's and B's Age = 4 : 3 = 4x : 3x

After 6 years A's age = 4x + 6

According to question 4x + 6 = 26

x = 4

5

B's Age = 3x = 3×5 =15

Answer 2

Given :

• Ratio of A's age to B's age is 4:3.
• 'A' will be 26 years old after 6 years.

To find :

• Present age of B's =?

Step-by-step explanation :

Let, the present age of, A's be 4x.

Then, the present age B's be 3x.

It is Given that,

'A' will be 26 years old after 6 years.

It means, A's age will be after 6 year's = 4x + 6.

According to the question,

➮ 4x + 6 = 26

➮ 4x = 26 - 6

➮ 4x = 20

➮ x = 20/4

➮ x = 5.

Therefore, We got the value of, x = 5.

Hence,

B's present age, 3x = 3 × 5 = 15 years

So, Option d). 15 years is the correct option.
