Common: 2^2 × 3 = 12

Explanation

4 workers finish in 6 days

1 worker will finish in 4 × 6 = 24 days

3 workers will finish in 24/3 = 8 days

Explanation

The volume of a cube is given by:

= 5³

= 5 × 5 × 5

= 125 cm³

Explanation

Compound interest (CI) is always more than simple interest (SI) when interest is calculated more than once or for multiple periods.

This is because CI earns interest on both principal and accumulated interest.

The difference between CI and SI increases with higher rates and longer time periods.

Explanation

1/3 of 1/2 of 90

= 1/3 × 1/2 × 90

= 1/6 × 90

= 15

Explanation

Total balls = 4 + 5 + 1 = 10

Red balls = 4

Probability = 4/10 = 2/5

Explanation

Numbers in order: 5, 7, 12, 18, 20

Middle value (3rd number) = 12

Explanation

SI = Principal × Rate × Time

= 1000 × 0.05 × 2

= 100

Explanation

Initial speed = 90 km/h

Final speed = 72 km/h

Decrease = 90 - 72 = 18 km/h

Percent decrease = (18/90) × 100% = 20%
