Q: Which of the following is a common multiple of 4 and 7?

(2) 28. To find a common multiple of 4 and 7, we look for a number that is a multiple of both. The least common multiple (LCM) of 4 and 7 is 28. Among the given options, only 28 is a multiple of both 4 (4 x 7 = 28) and 7 (7 x 4 = 28).

Q: Which figure has a line of symmetry?

(1) V. A figure has a line of symmetry if it can be folded along a line such that both halves match exactly. The letter 'V' has a vertical line of symmetry. The letters 'L', 'K', and 'N' do not have a line of symmetry.

Q: In 23.41, which digit is in the tenths place?

(4) 4. In a decimal number, the place values to the right of the decimal point are tenths, hundredths, thousandths, and so on. In the number 23.41, the digit immediately after the decimal point is 4, which is in the tenths place.

Q: Arrange the following from the smallest to the greatest.

(3) 7/100, 1/5, 0.83. To arrange the numbers, convert them to the same format, preferably decimals: 1/5 = 0.2 0.83 = 0.83 7/100 = 0.07 Now, arrange the decimal values from smallest to greatest: 0.07, 0.2, 0.83. This corresponds to 7/100, 1/5, 0.83.

Q: A rectangular cardboard measures 35 cm by 24 cm. A picture is pasted on it, leaving a border of 3 cm around it. Find the area of the picture.

(4) 522 cm². The cardboard has dimensions 35 cm by 24 cm. A 3 cm border is left around the picture. This means the picture's length will be 3 cm less on each side of the cardboard's length, so 35 - 3 - 3 = 29 cm. The picture's width will be 3 cm less on each side of the cardboard's width, so 24 - 3 - 3 = 18 cm. Area of the picture = Length × Width = 29 cm × 18 cm = 522 cm².

Q: Andy had 204 balloons. 2/3 of the balloons were blue and the rest were grey and white. There were 3 times as many grey balloons as white balloons. How many white balloons were there?

(1) 17. Total balloons = 204. Blue balloons = (2/3) × 204 = 2 × 68 = 136. Remaining balloons (grey and white) = 204 - 136 = 68. Let the number of white balloons be W. The number of grey balloons is 3W. Total grey and white balloons = W + 3W = 4W. Since 4W = 68, then W = 68 / 4 = 17. There were 17 white balloons.
