Question

Brad is 3 years older than Francis. The product of their ages is 154. Determine their ages.

Answer 1

Let Francis's age be x and Brad's age be 3x

The Product of their ages = 154

So ,

$\huge\blue{A}\red{n}\green{s}\red{w}\pink{e}\red{r}$

X × 3x = 154

4x = 154

x = 154÷4

x= 36

So Francis age = 36

Brad age = 36×3 = 108

Answer 2

Question:

Brad is 3 years older than Francis. The product of their ages is 154. Determine their ages.

Given:

• product of their ages=154
• Brad is 3 years older than Francis

Let:

• Age of Francis be x
• Age of Bard be x+3

Answer:

A/Q:

Age of Bard× Age of Francis=154

• x×(x+3)=154

• x²+3x=154

Let's split 3x into +14x and -11x

• x²+3x-154=0

• x²+14x-11x-154=0

• x(x+14)-11(x+14)=0

• (x-11)(x+14)=0

• x=11

• x=-14

So we aren't taking ages in negetive

• .°.x=11

As we know in starting we have take x as Financis age

• .°. Francis age=11✔

We know Brad is 3 years older than Francis

• .°. Brad age=x+3

• Brad age=14✔
