Question

Silvia was married 8 year ago. Today her age is 9/7 times to that time of marriage. At present his son&rsquo;s age is 1/6th of her age. What was her son&rsquo;s age 3 year ago?a)4 yrb)2 yrc)3 yrd)5 yre)None of the AboveCorrect answer is option 'C'. Can you explain this answer?

Answer

Let the age of Silvia during marriage = X
Present age = X + 8
A/Q -
X + 8 =9X/7
=> 7X + 56 = 9X
=> X = 28 year
Silvia age during marriage = 28 year
Present age = 28 + 8 =36 year
A/Q -
his son's age = 1/6 of 36 = 6 year
3 year ago,
his son's age = 6 - 3 = 3 years Option (C)

Answer

Silvia’s age 8 year ago = x
Present age = x + 8
x + 8 = 9/7 x
7(x + 8)= 9x
x = 28; 28 + 8 = 36
Son’s age = 1/6 * 36 = 6
Son’s age 3 year ago = 6-3 =3

Answer

's age is 1/4th of her age. What is her son's age?

Let's start by using algebra to represent Silvia's current age. Let x be her age at the time of her marriage. Then her current age is:

x + 8

We are told that her current age is 9/7 times her age at the time of her marriage:

x + 8 = (9/7)x

Multiplying both sides by 7 (to eliminate the fraction) gives:

7x + 56 = 9x

Subtracting 7x from both sides gives:

56 = 2x

Dividing both sides by 2 gives:

x = 28

So Silvia was 28 years old at the time of her marriage, and her current age is:

x + 8 = 36

Now we need to find her son's age. We are told that his age is 1/4th of her age, so we can set up the equation:

son's age = (1/4) * Silvia's age

Substituting in Silvia's current age, we get:

son's age = (1/4) * 36

Simplifying, we get:

son's age = 9

So Silvia's son is currently 9 years old.
