mber is divided by 5 then decreased by 5. It becomes - 2. Find the number.
12. Meenal has some money in her purse. If she adds 51 to it, it becomes to
some money in her purse. If she adds 51 to it, it becomes four times of the original amoun
What is the original amount in her purse?​

Answer 1

Answer:

let the number be x.

the equation will be like this :

$\frac{x}{5}$ - 5 = -2

(NOTE : We have to always take LCM of the two numbers before transposing the number to the other side.SO, First Take the LCM of 5 and 1[ any whole number the default denominator is 1].)

$\frac{x-25}{5}$  = -2

x - 25 = - 2 × 5

x - 25 = - 10

x = - 10 + 25

x = 15

Therefore, the number = 15.

Verification :

⇒ $\frac{15}{5}$ - 5 = -2

⇒ 3 - 5 = -2

⇒ - 2 = -2

Hence proved.

12) Let the original amount be x.

TO x if we add 51 two times, the number will be 4 times of x.

So, the equation goes like this :

x + 51 + 51 = 4x

take all the variables to one side.

⇒ 51 +51 = 4x - x

⇒ 102 = 3x

⇒ 102/3 = x

⇒ 34 = x

So, the original amount = ₹34.

Hope this helps you out!
