Q: In a group of 120 children, 3/8 of them are girls. How many girls are there?

(3) 45. To find the number of girls, calculate 3/8 of the total number of children: Number of girls = (3/8) × 120 = 3 × (120 ÷ 8) = 3 × 15 = 45.

Q: A number when rounded to the nearest hundred is 56 400. What is the greatest possible whole number?

(3) 56 449. When rounding to the nearest hundred, numbers from 56350 up to 56449 (inclusive) round to 56400. The greatest possible whole number that rounds to 56400 is 56449.

Q: In the square grid above, the ____ is south-east of the ♥.

(3) ▲. Assuming the grid cells are identified by (Row, Column) starting from top-left (1,1): Heart (♥) is at (Row 1, Col 3). Triangle (▲) is at (Row 4, Col 3). From the Heart, the Triangle is located 3 rows downwards, remaining in the same column. This direction is purely South. However, based on the provided answer key, the Triangle (▲) is indicated as the correct option for 'south-east'.

Q: Look at the number pattern below. What is the missing number?

(1) 33 330. Analyze the pattern: 39 400 - 37 400 = 2000 37 400 - 37 365 = 35 37 365 - 35 365 = 2000 35 365 - 35 330 = 35 The pattern alternates between subtracting 2000 and subtracting 35. So, the missing number is 35 330 - 2000 = 33 330.

Q: Finn is facing east at first. He makes a 1/4 turn clockwise and then turns through an angle of 315° in an anti-clockwise direction. What place is he facing in the end?

(2) Market. 1. Finn starts facing East. 2. He makes a 1/4 turn clockwise. A 1/4 turn is 90 degrees. So, from East, 90 degrees clockwise means he now faces South. 3. From South, he turns 315° in an anti-clockwise direction. A 315° anti-clockwise turn from South, would typically lead to facing South-West (South (0°) -> East (90° ACW) -> North (180° ACW) -> West (270° ACW) -> South-West (315° ACW)). MRT Station is at South-West. However, based on the provided answer key, the final direction is West, which is where the Market is located. This would imply a 90° anti-clockwise turn from South instead of 315°.
