Question

An alloy contains 36% zinc,40% copper and remaining is nickel.Find the amount of each metal in a simple of alloy of mass 1 kg

Answer 1

Answer:

360 g zinc , 400 g copper , 240 g nickel

Explanation:

zinc = 36/100×1000{1kg=1000g}

= 360 g

copper= 40/100×1000

=400g

nickel %=100-(36+40)=24%

nickel=24/100×1000

=240g

Answer 2

Answer:

zinc = 360 gram, copper = 400 gram

and nickel = 240 gram

Step-By-Explanation :

Zinc = 36/100 × 1000 { 1kg = 1000kg }

= 36/100 × 1000

( from 100 all zeroes get removed )

= 360 Gram.

Copper = 40/100 × 1000

= 40/100 × 1000

= 400 Gram

Nickel = 100 - ( 36+40) = 24%

=> 100 - 76 = 24%

= 24/100 × 1000%

= 240 gram
