Answer 2

Answer:

Kalu is 6 years old and Lalu is 9 years old

Step-by-step explanation:

STEP 1: Define x

Let x be the constant ratio

STEP 2: Find their age in term of x

Ratio of Kalu and Lalu = 2 : 3

Ratio of Kalu and Lalu = 2x : 3x

Kalu = 2x

Lalu = 3x

STEP 3: Solve x

Their product is 54

(2x)(3x) = 54

6x² = 54

x² = 9

x = √9

x = 3

STEP 4: Find their age

Kalu = 2x = 2(3) = 6 years old

Lalu = 3x = 3(3) = 9 years old

Answer: Kalu is 6 years old and Lalu is 9 years old
