Question

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

Answer 1

Step-by-step explanation:

$(2x + 20) \div 25 = 4$

$\frac{2x \times + 20}{25} = 4$

$2x + 20 = 100$

$2x = 100 - 20$

$2x = 80$

$x \ = 40$

so the no is 40
