Answer 1

Answer:

5000

Step-by-step explanation:

Laskha and Akshara are the renowned pair of friends for their vocabulary together.

Let the vocabulary of Laksha = x

Let the vocabulary of Akshara = y

x + y = 25000 ……..Eq (1)

After the accident, Laksha’s vocabulary reduced by 1/2

Laksha’s new vocabulary = 1/2x

1/2x + y = 20000 ……….Eq (2)

Solving Eq(1) & Eq(2);

  x + y = 25000

1/2x + y = 20000

(-)  (-)   (-)

————————

1/2 x = 5000

=> x = 10000

The number of words that Akshara had knowledge of = 10000

The number of words that Akshara has knowledge of = 5000
