Question

ARUN SUBTRACTS TWICE THE NUMBER OF BOOKS HE HAS FROM 30, HE FINDS THE RESULT TO BE 6. THEN HOW MANY BOOKS HE HAS?

Answer 1

Answer:

18 books

 Step-by-step explanation:

2x - 30 = 6

2x = 36

x = 18 book

Answer 2

It is given that when Arun subtracts twice the number of books he has from 30 the result comes out to be 6.

We have to find the number of books he has.

Let the number of books Arun has be 'x'

Then the condition can be mathematically represented as.

$30-2x=6$

To find 'x', we will have to rearrange the equation

$2x=30-6\\2x=24\\x=\frac{24}{2}\\x=12$

So, the number of books Arun has will be 12.
