Question

Andy has twice as many Marbles as Pandy have and sandy has half as many has andy and Pandy put together If Andy has 75 Marbles more than Sandy how many does each of them have

Answer 1

Suppose, Pandy has 'x' marbles.

Then, Andy has '2x' marbles.

And, Sandy has (2x + x)/2 = 3x/2 marbles.

Now, Andy has 75 marbles more than Sandy.

So, 2x = 3x/2 + 75

2x = (3x + 150)/2

4x = 3x + 150

x = 150......

So, number of marbles Pandy has = x = 150.....◆

And, number of marbles Andy has = 2x = 2×150 = 300......◆

And, number of marbles Sandy has = 3x/ 2 = 3×150/2 = 450/2 = 225......◆
