Question

what is communication ​

Answer 1

Answer:

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.$\:$

Explanation:

Communication is the act of developing meaning among entities or groups through the use of sufficiently mutually understood signs, symbols, and semiotic conventions. In Claude Shannon's and Warren Weaver's influential model, human communication was imagined to function like a telephone or telegraph.
