Equation Riddles

Five on many solutions are:

> (57 + 3)/.6

> √(7^6) - 3^5

> ceil(357 * sin (-6))

> floor(3*5*6.7)

> ((3!)!- 5!)/(6 mod 7)

40 or 96

Explanation:
Solution A :
Add the rhs of the last line to the current line
1 + 4 = 5
5 + 2 + 5 = 12
12 + 3 + 6 = 21
21 + 8 + 11 = 40

Solution B :
RHS = 1ST NUMBER + (1ST NUMBER * 2ND NUMBER)
1 + (1 x 4) = 5
2 + (2 x 5) = 12
3 + (3 x 6) = 21
8 + (8 x 11) = 96

First Equation
1Red-Flower + 1Red-Flower + 1Red-Flower = 60
Hence, 1Red-Flower = 20

Second Equation
Red-Flower + 5Blue-Petals + 5Blue-Petals = 30
20 + 10Blue-Petals = 30
10Blue-Petals = 10
Hence 1Blue-Petals = 1

Third Equation
5Blue-Petals + 2Yellow-Flower = 3
5 + 2Yellow-Flower = 3
2Yellow-Flower = 2
Hence, 1Yellow-Flower = 1

Required
Yellow-Flower + Red-Flower + 4Blue-Petals = ?
Hence, 1 + 20 + 4 = 25

Given
3Coke = 30 ....... Equation(1)
1Coke + 2 burger = 20 ....... Equation(2)
burger + 4 fries = 9 ....... Equation(3)
burger + fries * Coke = ?

Equation(1) => Coke = 10

Equation(2) => burger = (20-10)/2 = 5

Equation(3) => fries = (9-5)/4 = 1

Hence
burger + fries * Coke
= 5 + 1 * 10
= 5 + 10
= 15 ... Answer
