Explanation:

Present age of Panav = 30 years

Present age of Rama = 90 years

━━━━━━━━━━━━━━━━━━━━━━━━━━

Explanation :

G I V E N :

Rama is thrice as old as Panav.

Ten years ago, his age was four times Panav's age.

T OㅤF I N D :

Their present ages = ?

S O L U T I O N :

Let preset age of Panav = m years

So, present age of Rama = 3mㅤ(ℹ)

★ Before ten years :-

Panav's age = (m - 10) years

Rama's age = (3m - 10) years ㅤ(ℹℹ)

Also,

A/q,

Rama's age = 4(m - 10)ㅤㅤㅤㅤ(ℹℹℹ)

★ Comparing (ℹℹ) and (ℹℹℹ) :-

➵ㅤㅤㅤ3m - 10 = 4(m - 10)

➵ㅤㅤㅤ3m - 10 = 4m - 40

➵ㅤㅤㅤ-10 + 40 = 4m - 3m

➵ㅤㅤㅤ30 = m

➵ㅤㅤㅤm = 30

∴ Hence, present age of Panav = 30 ㅤㅤㅤyears.

★ Putting value of m in (ℹ) :-

➵ㅤㅤㅤPresent age of Rama = 3m

➵ㅤㅤㅤPresent age of Rama = 3 × 30

➵ㅤㅤㅤPresent age of Rama = 90 years

∴ Hence, present age of Rama = 90 ㅤㅤㅤyears.$\:$
