SSC MTS 14th July 2022 Shift-3

- There are three humans in the household.

- Each human has 2 legs, contributing 3 x 2 = 6 legs.

- Let the number of cats be "x".

- The number of dogs would then be twice the number of cats, or "2x".

- Cats have 4 legs each, and dogs also have 4 legs each.

- Therefore, the total leg count from cats is 4x, and from dogs is 4(2x) = 8x.

- Overall leg count: Human legs (6) + Cat legs (4x) + Dog legs (8x) = 42.

- Simplify the equation: 6 + 12x = 42.

- Reduce: 12x = 36.

- Divide by 12: x = 3.

- ?? Correct Answer: Option 4: 3
