Freddy is 4 years older than 8 5times his grandsons age. the sum of their ages is greater than 67. what is the youngest age freddy’s grandson can be?

The age of Freddy's grandson is 7 years.

Explanation:

We have given that,

Let the present age of grandson be x

Let the present age of Freddy's age be 8.5x+4

(∵  Freddy is 4 years older than  8.5 times  of his grandson)

According to question,

8.5x+4+x >67 (∵ we have given that sum is greater than 67)

⇒ 9.5x+4 >67

⇒ 9.5x > 67-4

⇒ 9.5x > 63

⇒ x >

⇒ x >

⇒ x > 6.6

As we know that age can't be in decimals so we use the nearest integer i.e. 7

So ,

The youngest age of Freddy's grandson age will be 7 years.

my guess would be b and d, but i didn’t actually get out the pen and paper. lol
