Question

madhulika though of a number double it and added 20 on it on dividing the result number by 25 she gets 4.find the number

Answer 1

Answer:

40

Step-by-step explanation:

Let us assume the number is  x.

Applying the condition :

On doubling the number and adding 20 to it, we get =  2x + 20

the resulting number =  2x + 20

Dividing the resulting number by 25, we gets 4

on formulating the equation we get ;

(2x + 20)/25 = 4  -------------------------equation 1

2x + 20 = 4*(25)

2x + 20 = 100

2x = 100 - 20

2x = 80

x = 80/2

x = 40

Therefore, the required number is 40

Answer 2

$\large {\green {\sf {\underline {\underline{Step-by-step \: Explanation}}}:-}}$

Let x be the number, Madhulika thought.

$» \: According \: to \: the \: question \frac{2x + 20}{25} = 4 \\ \\→2x + 20 = 4 \times 25 \\ \\→2x = 100 - 20 \\ \\→x = \frac{80}{2} = 40$

Hence, the required number is 40.
