Answer 2

QuestioN :

A Fraction become 1/3 When 1 is Subtracted from Numberator . If It become 1/4 When 8 is added to its denominator. Find the fraction ?

AnsWer :

5/12.

To Find :

Fraction ?

SolutioN :

Let,

• Numberator be N.
• Denominator be D

# Case 1.

• A fraction becomes 1/3 when 1 is Subtracted from Numberator.
• N - 1 / D = 1 / 3.

$\tt : \implies \dfrac{N - 1}{D} = \dfrac{1}{3}$

$\tt : \implies 3N - 3 = D \: \: \: \: \: - (1)$

$\rule{120}3$

# Case 2.

• It becomes 1/4 When 8 is added to its denominator.
• N / D + 8 = 1 / 4.

$\tt : \implies \dfrac{N }{D + 8} = \dfrac{1}{4}$

$\tt : \implies 4N = D + 8.$

$\tt : \implies 4N - 8 = D \: \: \: \: \: - (2)$

$\rule{120}3$

★ Compare both Equation ( 1 , 2 )

$\tt : \implies 3N - 3 = 4N - 8.$

$\tt : \implies 8 - 3 = N.$

$\tt : \implies N = 5.$

★ Now, Putting the value of N in Equation ( 1 )

$\tt : \implies 3N - 3 = D$

$\tt : \implies 3(5) - 3 = D$

$\tt : \implies 15 - 3 = D$

$\tt : \implies D= 12.$

Our Fraction become N / M → 5 / 12.
