Answer 1

Solution :

In the figure we can have a look at 3 different species that is • Tortoise (Shown in the first row) • Crab (Shown in the second row) and • Octopus (Shown in the third row)

_______________________________

Let's assume the value of Tortoise be x, Crab be y and Octopus be z

Starting From the First Row :

$\longrightarrow \sf \: x + x + x = 30$

$\longrightarrow \sf \: 3x = 30$

$\longrightarrow \sf \: x = \cancel\dfrac{30}{3}$

$\longrightarrow \sf \: x = \large\boxed{ \sf \: 10}$

Coming to the Second Row :

$\longrightarrow \sf \: x + y + y = 20$

$\longrightarrow \sf \: 10 + y + y= 20$

$\longrightarrow \sf \: 10 + 2y = 20$

$\longrightarrow \sf \: 2y = 20 - 10$

$\longrightarrow \sf \: 2y = 10$

$\longrightarrow \sf \: y = \cancel\dfrac{10}{2}$

$\longrightarrow \sf \: y = \large\boxed{ \sf \: 5}$

Coming to the Third Row :

We've taken value of Octopus as z but in this row there are 2 Octopuses. So, We'll take it as 2z

$\longrightarrow \sf \: z + z + y = 25$

$\longrightarrow \sf \: 2z + 5 = 25$

$\longrightarrow \sf \: 2z = 25 - 5$

$\longrightarrow \sf \: 2z = 20$

$\longrightarrow \sf \: z = \cancel\dfrac{20}{2}$

$\longrightarrow \sf \: z= \large\boxed{ \sf \: 10}$

Now, We've to find the value of Tortoise + Crab × Octopus

$\sf \longrightarrow x + y \times z$

$\sf \longrightarrow 10 + 5\times 10$

$\sf \longrightarrow 10+ 50$

$\bigstar \sf \: \large\boxed{ \sf60}$

Hence,Required Value is 60

Answer 2

Answer :--

Lets Assume That :-

→ Tortoise = x

→ Crab = y

→ Octopus = z.

Than, we Have Given That :-

→ x + x + x = 30

→ 3x = 30

Dividing both sides by 3 ,

→ x = 10 --------- Equation (1).

______________

Now, we have :-

→ x + y + y = 20

→ x + 2y = 20

Putting value from Equation (1) here,

→ 10 + 2y = 20

→ 2y = 20 - 10

→ 2y = 10

Dividing both sides by 2,

→ y = 5 ----------- Equation (2)

___________

In Last , we have Given :-

→ 2*Z + y = 25

Putting value from Equation (2),

→ 2z = 25 - 5

→ 2z = 20

Dividing both sides by 2,

→ z = 10 -------------- Equation (3).

___________

Now, we Have To Find :-

→ x + y * z

Putting values From Equation (1), (2) & (3),

→ 10 + 5 * 10

→ 10 + 50

→ 60 (Ans).

Hence, ( Tortoise + Crab + Octopus ) is 60.
