Question

An alloy is made of 37% copper,31% of zinc and the rest of nikle find the weight in 650g of alloy

Answer 1

Answer:

208 gram

Step-by-step explanation:

Zinc + copper + nickel = 100%

37% + 31% + nickel% = 100%

Nickel% = 100% - 68%

Nickel% = 32%

Weight of nickel in the alloy

= 32% of 650

= 32/100 × 650

= 208gram

208 gram is your answer

Hope it will help

Answer 2

Answer:

$given \: data \\ \% \: of \: zinc = 37\% \\ \% \: of \: copper = 31\% \\ \% \: of \: nickel = 100\% - (37 + 31) \\ = 100 - 68 \\ = 32 \\ total \: weight \: of \: alloy \: = \: 650 \: g \\ amount \: of \: nickel \: in \: the \: alloy | = \frac{32}{100} \times 650 \\ = 208 \: grams$
