Question

Gordon is twice as old as his sister Vivian if the sum of their ages is 24 how old is Gordon

Answer 1

Step-by-step explanation:

Let , Vivian's age be x years

Therefore, Gordon's age is 2x years

BTP,

x+2x =24

or, 3x = 24

or,. x=8

Therefore, Gordon's age is 8×2=16 years.

Answer 2

Answer:

Let ,

Gordan's age be x and Vivian's age be y.

ATQ.

x + y = 24. -------- 1

x = 2y. ------- 2

Using 2 in 1

2y + y = 24

3y = 24

y = 24/3

y = 8 ---------- 3

Put 3 in 2

x = 2 × 8

x = 16

Therefore,

Gordan's age is 16.
