Question

1/A + 1/B=1/12 , 1/A + 1/B +1/C = 1/8 Find 1/C​

Answer 1

Question:

If 1/A + 1/B = 1/12 and

1/A + 1/B + 1/C = 1/8 , then find the value of 1/C.

Answer :

1/C = 1/24

Given :

1/A + 1/B = 1/12 ---------(1)

1/A + 1/B + 1/C = 1/8 ------------(2)

Solution :

Putting 1/A + 1/B = 1/12 in eq-(2) ,

We get;

=> 1/A + 1/B + 1/C = 1/8

=> 1/12 + 1/C = 1/8

=> 1/C = 1/8 - 1/12

=> 1/C = (3 - 2)/24

=> 1/C = 1/24

Hence,

The required value of 1/C is 1/24.

Also,

C = 24.

Answer 2

Answer:

c= 24

1/12+1/c=1/8

1/8-1/12

12-8/96

4/96=1/24

c=24
