Answer 1

Answer:

hi

Step-by-step explanation:

Pramod's Present age is 12 years.

Step-by-step explanation:

Let,

Present age of Pramod = 3x

Present age of Deepak = 4x

After 8 years,

Age of Pramod = 3x + 8

Age of Deepak = 4x + 8

Also,

Their ages ratio will be 5 : 6

So,

\longrightarrow \: \dfrac{3x \: + \: 8}{4x \: + \: 8} \: = \: \dfrac{5}{6}⟶

4x+8

3x+8

=

6

5

\longrightarrow⟶ 6 (3x + 8) = 5 (4x + 8)

\longrightarrow⟶ 18x + 48 = 20x + 40

\longrightarrow⟶ 48 - 40 = 20x - 18x

\longrightarrow⟶ 8 = 2x

\longrightarrow⟶ x = 8 / 2

\longrightarrow⟶ x = 4

Present age of Pramod = 3x

\longrightarrow⟶ 3 (4)

\longrightarrow⟶ 12

Present age of Pramod = 12 years

∴ Pramod's Present age is 12 years
