Question

Twice of a number when decreased by 1 becomes 349 . find the number.
​

Answer 1

Data :

Let's take the number as x

Twice a number = 2x

Decreased by 1 = 2x - 1

Gives = 349

Solving :

= 2x - 1 = 349

= 2x = 349 + 1

= 2x = 350

= x = 350 / 2

= x = 175

Answer 2

Given :

• Twice a number

• Decreased by 1

• Result = 349

To find :

• The Number

According to the question :

Let the number be ' n '

• Twice the number = 2n

• Decreased by 1 = 2n - 1

• Result = 2n - 1 = 349

Equation :

⟹ 2n - 1 = 349

⟹ 2n = 349 + 1

⟹ 2n = 350

⟹ n = 350 / 2

⟹ n = 175

So, It's Done !!
