Explanation

A zoo has some lions and Parrots.

A zoo has x lions and y parrots

 The supervisor counted 15 heads and 50 legs. How many lions are there?

Heads

x + y = 15 

y = 15 – x

x = 4 legs and y has 2 legs

4x + 2y = 50

4x + 2(15-x) = 50

4x + 30 – 2x = 50

2x = 20

X = 20/2

X = 10

So x means lions, so there 10 Lions

CHECKING our answer***

  40 + 10 = 50 legs

Explanation

5/5 = 1

1 × 5/10 = 1/2

1/2 × 5/15 = 1/6

1/6 × 5/20 = 1/24

1/24 × 5/25 = 1/120

Explanation

To find speed, convert the time to hours and distance to kilometers:

Time = 2 minutes 30 seconds = 2.5 minutes = 2.5/60 = 1/24 hours

Distance = 750 meters = 0.75 kilometers

Speed = Distance / Time

= 0.75 / (1/24) = 0.75 x 24

= 18 km/hr

Explanation

The series is formed by incrementing the Roman numerals by 3:

V (5) + 3 = VIII (8)

VIII (8) + 3 = XI (11)

XI (11) + 3 = XIV (14)

XIV (14) + 3 = XVII (17)

So, the next number in the series is XVII.

Explanation

The series is formed by adding 1, 2, 3, 4, 5, ... to the previous term, so the next difference should be 5, making the next term:

• 3 + 1 = 4
• 4 + 2 = 6
• 6 + 3 = 9
• 9 + 4 = 13
• 13 + 5 = 18

Therefore, the completed series is: 3, 4, 6, 9, 13, 18.
