Suman got married 6 years ago. Today her age is 1(1/4) times her age a...
The answer is b.
Age of Kamla x
Age after six years x+6
x+6 = (5/4)x
4x+24=5x
x=24
Present age = 24+6
=30
Present age of son = (1/10)*30
= 3 years

Age of suman x
After six years x+6
x+6 = (5/4)x
4x+24 =5x
24 =5x-4x
24 =x
or x=24
present age =24+6 =30
present Age of son=(1/10)*30=30/10=3
Suman got married 6 years ago. Today her age is 1(1/4) times her age a...
Problem: Suman got married 6 years ago. Today her age is 1(1/4) times her age at the time of marriage. Her son's age is 1/10 times her age. Find her son's age.
Solution:
Let Suman's age at the time of marriage be x years.
Today's age of Suman = 1(1/4) x
= 5x/4
Suman got married 6 years ago. Therefore,
Age of Suman today = Age at the time of marriage + 6
5x/4 = x + 6
5x = 4x + 24
x = 24
Hence, Suman's present age = 5x/4 = 30 years
Son's age = (1/10) x 24 = 2.4 years
Therefore, the correct option is (d) 5 years.
Answer: The son's age is 5 years.
Explanation:
To solve this problem, we can use the following steps:
1. Let Suman's age at the time of marriage be x years.
2. Today's age of Suman = 1(1/4) x = 5x/4
3. Suman got married 6 years ago. Therefore, Age of Suman today = Age at the time of marriage + 6
4. 5x/4 = x + 6
5. Solve for x: 5x = 4x + 24
6. x = 24
7. Hence, Suman's present age = 5x/4 = 30 years
8. Son's age = (1/10) x 24 = 2.4 years (as given in the problem)
9. However, the options given for the son's age are all integers, so we need to round up 2.4 to the nearest integer, which is 2.4 ≈ 2.5 ≈ 3.
10. Therefore, the correct option is (d) 5 years.
