The average of 5 quantities is 6.
Therefore, the sum of the 5 quantities is 5 x 6 = 30.
The average of three of these 5 quantities is 8.
Therefore, the sum of these three quantities = 3 x 8 = 24
The sum of the remaining two quantities = 30 - 24 = 6.
Average of these two quantities = 6/2 = 3.

Given information:
- Average of 5 quantities = 6
- Average of 3 quantities = 8
To find:
- Average of remaining 2 quantities
Solution:
- Let's assume that the 5 quantities are a, b, c, d, and e.
- Using the given information, we can write:
a + b + c + d + e = 6 × 5 = 30 ... (1)
a + b + c = 8 × 3 = 24 ... (2)
- Subtracting equation (2) from equation (1), we get:
d + e = 30 - 24
= 6
- So, the sum of remaining two quantities is 6.
- To find their average, we need to divide this sum by 2:
Average of remaining two quantities = (d + e) / 2
= 6 / 2
= 3
- Therefore, the average of the remaining two quantities is 3.
Answer:
Option (C) 3 is the correct answer.
- Average of 5 quantities = 6
- Average of 3 quantities = 8
To find:
- Average of remaining 2 quantities
Solution:
- Let's assume that the 5 quantities are a, b, c, d, and e.
- Using the given information, we can write:
a + b + c + d + e = 6 × 5 = 30 ... (1)
a + b + c = 8 × 3 = 24 ... (2)
- Subtracting equation (2) from equation (1), we get:
d + e = 30 - 24
= 6
- So, the sum of remaining two quantities is 6.
- To find their average, we need to divide this sum by 2:
Average of remaining two quantities = (d + e) / 2
= 6 / 2
= 3
- Therefore, the average of the remaining two quantities is 3.
Answer:
Option (C) 3 is the correct answer.

The average of 5 quantities (a,b,c,d,e) is 6
a,b,c,d,e =5*6 = 30
the average of 3 quantities (a,b,c) is 8
a,b,c =3*8 =24
30-24 =6
the average of of the remaining 2(d,e)=6/2
=3
the answer is 3
a,b,c,d,e =5*6 = 30
the average of 3 quantities (a,b,c) is 8
a,b,c =3*8 =24
30-24 =6
the average of of the remaining 2(d,e)=6/2
=3
the answer is 3
