Answer 2

Answer:

When a cake weighing 1.250 kg is balanced against three small cakes, two of  which weigh 550 g and 450 g, the weight of the third cake would be 250g.

Step-by-step explanation:

Weight of the large cake is given as 1.250kg.

Since 1kg = 1000g,

Weight of the cake = 1.250 × 1000g = 1250g.

Now this cake is weighed against three smaller cakes. Weights of two of these cakes are given as 550g and 450g respectively.

Let the weight of the third cake be $x$ g.

Therefore,

$1250 = 550 + 450 + x$

$1250 = 1000+x$

$x= 1250-1000$

$x=250$

Hence the weight of the third cake is 250g.
