Soln:
Let a = mouse, b = cat and c = dog.

a + b = 10 ---(i)

a + c = 20 ---(ii)

b + c = 24 ---(iii)

From eqn (i) make a the subject.

a = 10 - b ---(iv)

Substitute eqn (iv) into equation (ii).

10 - b + c = 20.

Make b the subject:

b = c - 10 ---(v).

Then, substitute eqn (v) into eqn (iii):

c - 10 + c = 24.

2c = 34,

c = 17.

Eqn (v): b = c - 10, b = 17 - 10 = 7.

Eqn (iv): a = 10 - b, a = 10 - 7 = 3.

Therefore: a + b + c = 17 + 7 + 3 = 27.

The answer is 27.
