Here's the puzzle in the screen shot below.

Solution:
Equation one.
3 horses = 30
Horse = 10.

Equation two
10 + 4 magnet = 18
4 magnet = 8.
Magnet = 2.

4 - pair of shoes = 2

A pair of Shoes = 2.
If a pair of shoes= 2, implies a shoe = 1
Hence, Horse= 10,

Magnet = 2.

Shoe = 1.

A shoe + A horse × A magnet= ?
1 + 10 × 2= ?
1+ 20 = ?
