Answer 1

Given :

• The ratio of weights of copper and zinc in brass is 13:7.

$\: \:$

To find :

• Find the weight of zinc in a brass utensil weighing 700 gm.

$\: \:$

Solution :

• As in the question Ratio of copper and zinc in brass is 13 : 7. Firstly we will the Cooper be 13x and Zinc be 7x. Then, weight of copper + Weight of zinc = 700. We will get the value of x and then put the values in the Given Ratios.

$\: \:$

$\large \pink \star \:$ Let weight of copper = 13x

$\large \pink \star \:$Let weight of zinc = 7x

$\large \pink \star \:$Weight of brass in utensil = 700gm

$\: \:$

Weight of copper + zinc = 700gm

$\: \:$

➤ 13x + 7x = 700

➤ 20x = 700

➤ x = 700/20

➤ x = 35

$\: \:$

Weight of zinc = 35 × 7 = 245gm

$\therefore$ Weight of zinc in brass is 245gm
