There are two numbers 11 if you add them and three if you. Subtract

Answer»

Answer:

Hiii FRIEND,

Let the two numbers be X and Y.

1 is ADDED to each Number then the numbers becomes X+1 and Y+1

According to question,

X + 1/Y+1 = 1/2

2(X+1) = 1(Y+1)

2X + 2 = Y +1

2X -Y = 1-2

2X - Y = -1---------(1)

5 is subtracted to each NUMBERS then the numbers becomes (X-5) and (Y-5).

According to question,

(X-5)/(Y-5) = 5/11

11(X-5) = 5(Y-5)

11X - 55 = 5Y - 25

11X - 5Y = -25+55

11X - 5Y = 30---------(2)

From equation (1) we get,

2X - Y = -1

2X = -1 + Y

X = -1+Y/2--------(3)

putting the value of X in equation (2)

11X - 5Y = 30

11 × (-1+Y/2) - 5Y = 30

-11 + 11Y/2 - 5Y = 30

-11+11Y - 10Y = 30 × 2

Y - 11 = 60

Y = 60+11

Y = 71

Putting the value of Y in equation (3)  

X = -1+Y/2 => -1 + 71/2 => 70/2

X = 35

Hence,

Number are 71 and 35.
