Answer 2

Answer:

The present age of Benny is 42 years .

Step-by-step explanation:

Given as :

The age of the Benny's sister = S = 24 years

The age of the Benny = B = 125% of Benny's sister age

Or, B = $\dfrac{125}{100}$ × S

Or, B = 1.25 × 24 years

Or, B = 30 years

So, The age of Benny = B = 30 years

Again

The present age of Benny is 12 years older than earlier age

Let The present age of Benny = B'

So, B' = 12 years + B

Or, B' = 12 years + 30 years

Or, B' = 42 years

So, The present age of Benny = B' = 42 years

Hence , The present age of Benny is 42 years . Answer
