Question

Madhulika thought of a number, doubled it and added 20 to it. On dividing the result by 25, she gets 4. What is the number she thought?

Answer 1

Answer:

40

Step-by-step explanation:

Let the no. =x

if we double the no. =2x

ATQ

$\frac{2x + 20}{25} = 4 \\ 2x + 20 = 4 \times 25(cross \: multiplication) \\ 2x + 20 = 100 \\ 2x = 100 - 20 \\ 2 x = 80 \\ x = \frac{80}{2} = 40$
