Question

Ten gram of an alloy of metals A and B contains 7.5 gm of metal A and the rest is
metal B. Find the ratio between :.
(i) the weights of metals A and B in the alloy.
(ii) the weight of metal B and the weight of the alloy.​

Answer 1

Answer:

(i) weight of metal B = ( 10 - 7.5 ) g

= 2.5 g

Ratio :-

weight of metal A : weight of metal B

=> 7.5 : 2.5

=> 3 : 1

(i) answer = 3:1

(ii)

weight of metal B = 2.5 g

weight of alloy. = 10 g

Ratio :-

2.5 : 10

=> 1 : 4

(ii) answer = 1:4

Answer 2

Step-by-step explanation:

We know that

Total weight of A and B metals = 10 gm A weight - 7.5 gm B weight

So we get

= 10 – 7.5

= 2.5 gm

Ratio between the weight of A and B in the alloy = 7.5: 2.5

It can be written as= 1075 : 1025

So we get ,

=3:1
