Question

The ratio of weight of copper and zinc in brass is 13:7 find the weight of zinc in a brass.koi hai ​

Answer 1

Assume :

• Let the weight of the copper be 13x.

• Weight of zinc be 7x.

According to question our equation is :

$\sf{13x + 7x = 700}$

$\sf20x = 700$

$\sf{x = 35}$

Weight of zinc in brass = 7 x 35 = 245 gm

Hence Solved✅
