Answer 2

Answer:

option (b)

Step-by-step explanation:

Taking 1 black block to be x.

If the white block is z and the grey block is y.

Then from the first balance,

$3x = 2z\\\\z = \frac{3}{2}x$

From the second balance,

$3y = 2x\\\\y = \frac{2}{3} x$

Now in the third balance, there are 4 white blocks then it will be equal to -

$4z = 4\times\frac{3}{2} x = 6x$

Checking options-

Option (a)

4 black blocks + 2 grey block

$4x + 2\times\frac{2}{3} x = \frac{16}{3}x$

Option (b)

2 black blocks + 6 grey blocks

$2x + 6\times\frac{2}{3} = 6x$

We got the same value so, This is the correct option.

Option (c)

3 black blocks + 3 grey blocks

$3x + 3\times\frac{2}{3}x = 5x$

Option (d)

6 grey blocks

$6\times\frac{2}{3} x = 4x$

So the desired option is (b).
