ANSWER:--------
given the ratio between zinc and copper in brass is 13 : 7
let the quantity of zinc and copper be 13x and 7x respectively.
→ 13x + 7x = 100kg
→ 20x = 100kg
→ x = 100/20
→ x = 5kg
hence, quantity of zinc present in 100kg brass = 13x = 13 × 5 = 65kg

pieces of zinc =13x
pieces of copper=7x.
13x+7x=100
20x=100
x=100÷2
x=50
piecesof zinc =13×50
=650
