Question

The ratio of Zinc and brass in an alloy is 7:9. If the Weight of the alloy is 160 Kg, find the weight of the zinc in the alloy

Answer 1

Step-by-step explanation:

the weigh of the zinc in the alloy is 80kg

Answer 2

$\huge{\mathcal{\blue{\underline{Answer}}}}$

Let the composition of zinc and brass be 7x,9x

$7x + 9x = 160 kg\\ 16x = 160kg \\ x = \frac{160kg}{16} \\ x = 10kg$

Composition of Zinc :

$= 7x = 7(10kg) = 70kg$

Composition of brass :

$= 9x = 9(10kg) = 90kg$
