6.
Alloy of brass contains copper and zinc in the ratio 13:7. In 1.5 kg of brass vessel
the weight of zinc will be = ?​

Answer 1

Given:

The alloy of brass contains copper and zinc in the ratio 13:7.

To find:

In 1.5 kg of the brass vessel, the weight of zinc will be =?​

Solution:

From the given ratio of zinc and copper in the brass alloy let,

"13x" → represents the weight of the copper

"7x" → represents the weight of the zinc

The given weight of the brass vessel = 1.5 kg

Now, as per the question, we get

$13x + 7x = 1.5$

$\implies 20x = 1.5$

$\implies x = \frac{1.5 }{20}$

$\implies x = 0.075\:kg$

∴ $7x = 7 \times 0.075 = 0.525\:kg$

∵ $\boxed{\bold{1 \:kg = 1000 \:gms}}$

∴ 0.525 kg = $\frac{0.525}{1000} = 525 \:gm$

Thus, the weight of zinc will be → 525 gm.
