Question

5. An alloy contains 24% copper, 35% nickel and
rest is zinc. Find the quantity of zinc in 15 kg
of alloy​

Answer 1

Answer:

Cooper=24%

nickel=35%

zinc=(24+35)%-100%=41%

quantity of zinc in 15 kg of alloy=41%of 15000gm

=41/100 *15000g

=41*150

= 6150gm

= 6kg150gm

Answer 2

Answer:

Given in the question:-

• Copper=24%
• Nickel=35%
• Total weight are= 15 kg

SO,:-

• Zinc will be 59%, Because

$(24 + 35) - 100 = 59$

• The 1% is equal to 150g, Because

$\frac{15000}{100} = 150$

Solution:-

• The persentage of zinc × 1% i.e. 150

$59 \times 150 = 8850$

• 8850g will be converted into 8.85 kg.

$\frac{8850}{1000} = 8.85$

The Zinc is 8.85 kg out of 15 kg. The presentage of zinc is 59 kg.
