Answer 2

Let us assume that initially A had a chocolates, B had b chocolates, C had c chocolates and D had d chocolates.

Given: a=b+80a=b+80

We need to find: c−d

so , 2a/3 = 34(b+a3)=45(c+b4+a12)=d+15(c+b4+a12)

So now take this one at a time.

2a3=34(b+a3)2a3=34(b+a3)

But you know that a = b + 80. So substitute that into this equation.

2b+1603=34(b+b+803)2b+1603=34(b+b+803)

Simplifying this we get:

3b+a4=4c5+b5+a153b+a4=4c5+b5+a15

Substituting a = 80 and b = 100 in this, we get c = 110

Now solve for the last part of the equation:

45(c+b4+a12)=d+15(c+b4+a12)45(c+b4+a12)=d+15(c+b4+a12)

Taking everything except d to the left hand side we get:

35(c+b4+a12=d35(c+b4+a12=d

Now substituting values of a, b and c into the equation as 180, 100 and 110 respectively we get the value of d as:

d=90d=90

Thus c−d=110−90=20.c−d=110−90=20.
