Question

Leo is thrice as old as Sandra. The difference of their ages is 10. Find their present ages.

Answer 1

Answer:

5 years, 15 years.

Step-by-step explanation:

Let the age of Sandra be "X".

Leo's age = 3x

Difference of their ages = 10 years.

3x - X = 10

2x = 10

X= 10/2

X = 5

Hence, Sandra's age = 5 years

Leo's age = 3(5)

= 15 years.

Answer 2

Answer:

Sandra's age = 15 years

Leo's age = 5 years

Step-by-step explanation:

Let the age of Leo be '3x' years,

then age of Sandra is 'x' years.

So,

according to the question,

Difference of age between them is 10,

so,

here we make a linear equation,

=> 3x-x=10

=> 2x=10

=> x=5

So, age is 5 years and sandra's age is 3 times, i.e 15 years.
