Three numbers A, B and C are in the ratio 7: 2: 4. The sum of the three numbers is 104. What is the number C?

C = 32

Step-by-step explanation:

The numbers are in the ratio 7 : 2 : 4 = 7x : 2x : 4x ( x is a multiplier ) , then

7x + 2x + 4x = 104

13x = 104 ( divide both sides by 13 )

x = 8

Thus C = 4x = 4 × 8 = 32

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4
