Answer:

25.55

Step-by-step explanation:

Let us take the number he thinked of be x .

<u>On </u><u>doubling</u><u> </u><u>it </u><u>:</u><u>-</u><u> </u>

→ N = 2x

<u>On </u><u>adding</u><u> </u><u>1</u><u>9</u><u> </u><u>:</u><u>-</u><u> </u>

→ N = 2x + 19

<u>According</u><u> to</u><u> Question</u><u> </u><u>:</u><u>-</u><u> </u>

→ 2x + 19 = 70.1

→ 2x = 70.1 - 19

→ 2x = 51.1

→ x = 51.1/2

→ x = 25.55

<h3>Hence the required answer is 25.55</h3>
