Question

if you know that then please rply me show this with method and statement if enyone answer anything else then I will report the answers those who answered correctly and 1st i mark them as brainleast please answer fast ​

Answer 1

Solution:

Let -

• Age of ramu = 4x
• Age of raghu = 5x

8 years from now -

• Age of ramu = 4x + 8
• Age of Raghu = 5x + 8

According to the question,

→ (4x + 8)/(5x + 8) = 5/6

→ 6(4x + 8) = 5(5x + 8)

→ 24x + 48 = 25x + 40

→ 24x - 25x = 40 - 48

→ -x = -8

→ x = 8

As we supposed,

★ Age of ramu = 4x

→ Age of ramu = 4 × 8

→ Age of ramu = 32 years

★ Age of raghu = 5x

→ Age of raghu = 5 × 8

→ Age of raghu = 40 years.

Answer 2

$\rm\large\purple{\underline{ Question : }}$

Present ages of Ramu & Raju are in the ratio 4:5 later eight years, the ratio of their ages 5:6. Find their present ages.

$\rm\large\purple{\underline{ Solution : }}$

★ Given that,

☯ Ages of Ramu and Raju in ratio = 4:5

• Age of Ramu = 4x
• Age of Raju = 5x

☯ Later 8 years their ages be :

• Age of Ramu = (4x + 8)
• Age of Raju = (5x + 8)

↪ After 8 years the ages of Raju ang Ramu in ratio : 5:6

★According to the question,

$\bf\:\implies \frac{4x + 8}{5x + 8} = \frac{5}{6}$

$\bf\:\implies 6(4x + 8) = 5(5x + 8)$

$\bf\:\implies 24x + 48 = 25x + 40$

$\bf\:\implies 48 - 40 = 25x - 24x$

$\bf\:\implies x = 8$

★ Now,

$\tt\:\implies Age \: of \: Ramu = (4x + 8)$

• Substitute the value of x.

$\bf\:\implies 4(8) + 8$

$\bf\:\implies 32 + 8$

$\bf\:\implies 40$

$\tt\:\implies Age\:of\:Raju\:=\: (5x + 8)$

• Substitute the value of x.

$\bf\:\implies 5(8) + 8$

$\bf\:\implies 40 + 8$

$\bf\:\implies 48$

$\underline{\boxed{\sf{\red{ \therefore Present\:age \: of \: Ramu = 40,Present\:age \: of \: Raju = 48}}}}\:\orange{\bigstar}$
