Question

A+ b = 13 c/b=10 a+b+c=33

Answer 1

given:

a + b= 13 ----(1)

$\frac{c}{b} = 10 - - - (2)$

a + b + c=33

to find: value of a, b and c

from equation (1)

$a= 13 - b$

and from equation (2)

$c = 10b$

put the values in equation (3)

we get,

$(13 - b) + b+ 10b = 33$

on solving this

we get,

a =11

b=2

c=20

Answer 2

a + b + c =33

13 + c = 33

c = 20

c/b = 10

20/b = 10

b = 2

a + b = 13

a + 2 =13

a = 11
