Question

Q.11 present ages of Anu and Raj is in the ratio 4:5. Eight years from now
the ratio of their ages will be 5:6. Find their present ages?​

Answer 1

Given:

• Present ages of Anu and Raju are in ratio = 4:5
• After eight years the ratio of their ages will be = 5:6

━━━━━━━━━━━━━━━

Need to find:

• Their present ages =?

━━━━━━━━━━━━━━━

Solution:-

• Let Anu's age be = 4x years

• Let Raj's age be = 5x years

━━━━━━━━━━━

Then,

After eight years:-

→ Anu's age = 4x +8 years

→ Raj's age = 5x + 8 years

→ Ratio of their ages = (4x + 8) : (5x + 8)

━━━━━━━━━━━

Also given:-

→ The ratio after eight years = 5:6

→ $\dfrac{4x + 8}{5x + 8} = \dfrac{5}{6}$

→ $24x + 48 = 25x + 40$

→$25x - 24x = 48 - 40$

→$\purple{\bold{\boxed { x= 8}}}$

━━━━━━━━━━━

Anu's present age :

= 4x

= 4 × 8 years

= $\red{\bold{\boxed {\large{ 32years }}}}$

Raj's present age:

=5x

= 5× 8 years

= $\red{\bold{\boxed{\large{40 years}}}}$
