Question

Two thirds of the number is increased by 9 , the sum will be 19, find the number .

Answer 1

Step-by-step explanation:

Let the required numbers be x.

Therefore, two third of the number =

$= \frac{2}{3} x \\ now \: \\ \frac{2}{3} x + 9 = 19 \\ \frac{2}{3} x = 19 - 9 \\ \frac{2}{3} x = 10 \\ x = \frac{3 \times 10}{2} \\ x = 3 \times 5 \\ x = 15 \\ thus \: the \: required \: no \: is \: 15.$

Answer 2

Answer:

Let the number be 'x'

2/3x + 9 = 19

2/3x = 19 - 9

2x = 10 x 3

x =  30/2

therefore, x = 15
