Answer 1

the weight of zinc in the brass utensil is 245 gm

ratios:

13:7

sum of the ratios= 13+7=20

weight of copper= 13/20x700

=455

weight of zinc =7/20x700

=245

Step-by-step explanation:

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

Let the weight of the copper be 13x.

Weight of zinc be 7x.

From the given information,

Given weight of brass = 700 gm

Weight of copper in brass + weight of zinc in brass = 700 gm

13x+7x=700∴ 20x=700∴ x=35

∴ Weight of zinc in brass = 7 × 35 = 245 gm

Hence, the weight of zinc in a brass utensil is 245 gm.
