Answer 1

Let the locket be x.
Let the Gorilla with locket be y.
Pair of bananas be z.

Given,
x + x + x = 30
3x = 30
x = 10 .

Now,
x + y + y = 20
10 + y + y = 20
y = 5 .

Also, y + z + z = 17
5 + 2z = 17
2z = 12
z = 6 .
Pair of bananas = 6
One banana = 3 .

Also, gorilla without locket = 5 - 10 = -5 .

Now,
10 - 5 * 3
= 10 - 15
= -5 .

Hope helped!

Answer 2

Heya...
Here is your answer ----


(1) Let the locket's value be x
Then,
x + x + x = 30
3x = 30
x = 30/3
x = 10

Value of 1 locket = 10

(2) Locket = 10
Let the value of Gorilla with Locket be y

Now,
10 + y + y = 20
2y + 10 = 20
2y = 20 - 10 = 10
y = 10/2
y = 5

Value of 1 gorilla with Locket = 5


(3) Let 2 banana's value be z

Then, 5 + z + z = 17
2z + 5 = 17
2z = 17 - 5 = 12
z = 12/2
z = 6

Value of 2 banana = 6
Value of 1 banana = 6/2 = 3


• Gorilla with Locket = 5
Locket = 10
Value of Gorilla without Locket = 5-10 = -5


(4) Value of Locket = 10
Value of Gorilla without Locket = -5
Value of 1 banana = 3

10 + (-5) × 3
= 10 + (-15)
= 10-15
= -5
