Question

Nikhil and his friends are playing Treasure Hunt. The solution to the equation $(4x-5)=2\left(x\right)+5$ gives the floor in which the treasure is kept.

In which floor is the treasure kept?

• A. Second floor
• B. Third floor
• C. Fourth floor
• D. Eighth floor

Answer 1

The correct option is A

Second floor

The solution to the equation.

$3(4x-5)=2x+5$ gives us the floor in which the treasure is kept.

Solve the equation $3(4x-5)=2x+5$

$3(4x-5)=2x+5$

$12x-15=2x+5$

$12x-2x=15+5$

$10x=20$

$x=\frac{20}{10}$

$\therefore x=2$.

As x = 2, the treasure is kept in the 2nd floor.
