Question

the number of four legged pets in a locality were 2more than 3 times the number of two legged pets if the total number of legs of the pet in the locality is 358 then find the number of four legged pets

Answer 1

Let the Number of Two Legged Pets be : H

Given that : The Number of Four legged pets in the locality are Two More than Three times the Number of Two legged pets.

⇒ Number of Four Legged pets = (3 × Two legged pets) + 2

⇒ Number of Four Legged pets = 3H + 2

Given that the Total Number of Legs of the Pets = 358

We know that Each Two Legged Pet has 2 Legs and Each Four Legged pet has 4 Legs.

(Number of 2-Legged Pets) × 2 + (Number of 4-legged pets) × 4 = 358

⇒ (H × 2) + (3H + 2) × 4 = 358

⇒ 2H + 12H + 8 = 358

⇒ 14H = 350

⇒ H = 350/14 = 25

So, Total Number of Two legged Pets = 25

Total Number of Four legged Pets = 3H + 2 = (3 × 25) + 2 = 75 + 2 = 77

Answer 2

Step-by-step explanation:

let the number of 2 legged PET be x

4 legged pets = 3x + 2

• 2x + 4 ( 3x + 2 ) = 358
• 2x + 12x + 8 = 358
• 14x + 8 = 358
• 14x = 358 - 8
• 14x = 350
• x = 350 / 14
• x =25
