1) 10+10+10 = 30
2) 5 +5+10=20
3) 4+4+5=13
4) 5+19*2 = 43

Don’t forget the order of operations(PEMDAS)
Parenthesis
Exponent
Multiplication
Division
Addition
Subtraction

so,
5+19*2 =
5+38=43
How is the man 19?

1) 10+10+10 = 30
2) 5 +5+10=20
3) 4+4+5=13
4) 5+5*2 = 15,

Lets say, a shoe as x, boy as y, and a snack packet as z,
So the equation are,
1) 2x+2x+2x=30
x = 30/(2+2+2)
x = 5;
2) y + y +2x =20;
2y+2(5)=20;
y = 5;
3) 2z + 2z + y = 13;
4z + 5 = 13
z = (13-5)/4
z = 2;

So for the last equtation
x + y * z =?

5+5*2 = 15 //using the math operations precedence, Multiplication executes first.

Shoes pair 10 so 10+10+10 =30
Second di 10 +5+5=20 so man is 5
Next Di 4+4+5=13 so pair pop corn pack of two is 4
So one shoe is 5 and man 5 + 4 popcorn pack of two + 10 pair shoes =19 and 2 one popcorn pack

As per BODMAS RULE
5+(5+4+10)*2 =43
