Check the answer below:

119 is the answer.

Explanation
Equation 1: 9 + (9 + 9) + 9 = 36 (So the value of APE = 9. Also you can see there are two Ape’s in the middle portion of this equation.

Equation 2: 9 + 9 + 9 = 27 (So the value of BUG = 9. Also you can see there are nine dots above the body of the bug; so each dot has a value of 1.

Equation 3: 12 + 12 + 6 = 30 (So the value of a ROSE = 6. If you look this equation closely, you can see that there are two Roses in the first and second part of this equation.

Equation 4: (1 + 9 + 18) + 13 x 7

In the first part of 4th equation you can see there is an APE and 3 Roses. Also you can see a Dot in the forehead of the Ape which has a value of 1.
In the second part of 4th equation, you can see the bug which has 13 Dots in its body (including 2 dots in both the legs)
In the third part of 4th equation, you can see one Rose with a Dot at its bottom.

=> 28 + 13 x 7

Applying BODMAS rule,
=> 28 + (13 x 7)
=> 28 + 91
= 119
