Question

A+b+100=350 if a=2b and b=2c what is the value of c

Answer 1

let A+B+100=350 be equation (1)
and b=2c as equation (2)
now, a=2b (given)
putting value of a in equation (1)
2b+b+100=350
3b=350-100
b=250/3
b=84 (approx)
now, putting value of b in equation (2)
84=2c
84/2=c
c=42 (approx)

Answer 2

 Your Answer  ^_^    ^_^ ↓↓.

Given :- A + B + 100 = 350.
              A = 2B.
             B = 2C.

To Find :- Value of C.

Solution :- 
              B+ 2B +100 = 350
              3B = 250 
              B = 250/3 
              B = 83.3

               C = B/2
              C = 42.56
