Question

Keena current age is 150% of what it is used to be 20 years ago and 90% of what it will be 20 years later how old is Keenan currently ?

Answer 1

30years

Step-by-step explanation:

A’s present age = 150%

A's age 10 years ago = 100%

150% - 100% = 10 years

A's present age = 50% *3 = 150% = 10*3 = 30 years.

Answer 2

Data is inconsistent as for Keena current age is 150% of what it is used to be 20 years ago current age is 60 years and

for Keena current age is 90% of what it will be 20 years later current age is 180 years

Given:

Keena current age is 150% of what it is used to be 20 years ago

90% of what it will be 20 years later

To Find:

Current Age

Solution:

Step 1:

Assume that Keena current Age = x Years

Hence Age 20 years ago  = x - 20

Age 20 years later  = x + 20

Step 2:

Current age is 150% of Age 20 years ago hence

(150/100) (x - 20)  = x

=> (3/2)(x - 20) = x

=> 3x - 60  = 2x

=> x = 60

Current age is  60 Years

Step 3:

Current age is 90% of Age 20 years later hence

(90/100) (x + 20)  = x

=> (9/10)(x + 20) = x

=> 9x + 180  = 10x

=> x = 180

Current age is  180 Years

Hence , Data is inconsistent  as for one statement current age is 60 years and for other statement current age is 180 years

Each individual statement is enough to solve.

And both statements are not giving same solution.
