Math, asked by Guddukumar11, 1 year ago

तीन संख्याओं का औसत 28 है, पहली संख्या दूसरी संख्या से आधी है, तीसरी संख्या क्या है?

Guddukumar11: और सब लोग ध्यान से देखें

Guddukumar11: तीन संख्याओं का कुल योग = 28 × 3 = 84

Guddukumar11: माना दूसरी संख्या =x, तब, पहली संख्या= x/2. तथा तीसरी संख्या= 2x.

Guddukumar11: इसलिए

Guddukumar11: x+x/2+2x = 84

Guddukumar11: या, 7x =168

Guddukumar11: या

Guddukumar11: x =24

Guddukumar11: So now 3rd num

Guddukumar11: 2× 24 = 48 ans.

Answer:

Step-by-step explanation:

Let the second term be x

We are given that the first term is half of second term

So, First term = x/2

We are given that The third term is twice the second term

So, Third term = 2x

Now we are given that the average of 3 terms is 28

So, $\frac{\frac{x}{2}+x+2x}{3}=28$

$x=24$

Third term = 2x=2(24)=48

Hence the third term is 48
