Answer 2

Hey mate here is your answer.....

(i) Let the original fraction be x / y

Then, (x+1) / (y+1) = 2/3 (given)

So, 3x +3 = 2y +2

Or, 3x- 2y = 2–3 = -1

Or, 3x - 2y = -1. Eq.1

Also,

(x-1) / (y-1) = 1/2 (given)

So, 2x-2 = y-1

Or, 2x - y = -1 + 2 = 1

Or, 2x- y = 1 Eq. 2

Multiplying EQ. 2 by 2, we have:

4x - 2y = 2 Eq. 3

Subtracting EQ. 1 from EQ. 3, we get:

x=3

Substituting the value of x in EQ.1, we

get:

9- 2y = -1

Or, 2y = 9+1 = 10,

Or, y = 5.

So, the original fraction ( x / y ) is 3 / 5

Check:

Adding 1 to the numerator as well as

denominator of original fraction 3/ 5,

we get : (3+1) / (5+1)= 4 / 6 = 2/3 ✓

By subtracting 1 from the numerator as

well as denominator of the original

fraction 3 / 5, we get :

(3–1) / (5 - 1) = 2 / 4 = 1 / 2 ✓..

(ii) 2 ladoos.....
