Answer 1

..Question..

The ratio of the weights of copper and zinc in brass is 13:7 . Find the weight of zinc in a brass utensil weighing 500 gms.

..Answer..

Given ,

ㅤㅤㅤ ㅤㅤRatioㅤㅤㅤ = 13:7

ㅤㅤㅤㅤㅤ Total weight = 500 g

☯︎ Let the weight of the metals be x

•°•ㅤ The weight of copper = 13x

ㅤㅤ The weight of zinc ㅤ = 7x

•°• According to the Question ,

ㅤㅤㅤ➪ Copper + Zinc = Brass

ㅤㅤㅤ➪ 13x + 7x = 500 g

ㅤㅤㅤ➪ 20 x = 500

ㅤㅤㅤ➪ x = 500 / 20

ㅤㅤㅤ➪ x = 50 / 2

ㅤㅤㅤ➪ x = 25 ㅤㅤㅤ---------- ( 1 )

•°•

➪ Amount of Copper = 13x

ㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤ = 13 × 25 ( from 1 )

ㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤ = 325

➪ Amount of Zinc = 7x

ㅤㅤㅤㅤㅤㅤㅤㅤㅤ= 7 × 25 ( from 1 )

ㅤㅤㅤㅤㅤㅤㅤㅤㅤ= 175

•°• Amount of Copper = 325 g

➪ Amount of Zincㅤㅤ= 125 g

i.e , Total Amount = ( 325 + 125 ) g

ㅤㅤㅤㅤㅤㅤㅤㅤ = 500 g
