Logical Reasoning

Q1: Veer is in a line. If he is 6th from the front and 12th from the back, how many people are there in total in the line?
(a) 20
(b) 17
(c) 19
(d) 18

Maths Olympiad Previous Year Paper -1 | Mathematics Olympiad Class 4  View Answer

Ans: (b)

  • To find the total number of people in the queue, we can add Veer's position from the front and his position from the back, then subtract 1 (since Veer is counted in both positions).
  • So, the calculation is: 6 (from the front) + 12 (from the back) - 1 = 17.
  • This means there are a total of 17 people in the queue.
  • Thus, the correct answer is 17.

Q2: Find the combination of numbers so that the given letters are arranged accordingly to form a meaningful English word. 
K A T R M E
(a) 5, 2, 4, 1, 6, 3
(b) 5, 2, 1, 4, 6, 3
(c) 3, 4, 6, 2, 1, 5
(d) 4, 2, 3, 1, 6, 5

Maths Olympiad Previous Year Paper -1 | Mathematics Olympiad Class 4  View Answer

Ans: (a)

  • The letters K, A, T, R, M, E can be rearranged to form the word "MARKET".
  • Using the combination 5, 2, 4, 1, 6, 3 corresponds to the letters M, A, R, K, E, T respectively.
  • This arrangement gives us a meaningful English word, which is "MARKET".
  • Other combinations do not yield a valid English word when the letters are rearranged.

Q11: Aman went on a 15-day journey. He stayed for 7 days in Manali and the remaining days in Shimla. What portion of his trip did he spend in Shimla?
(a) 8/7
(b) 7/8
(c) 8/15
(d) 7/15

Maths Olympiad Previous Year Paper -1 | Mathematics Olympiad Class 4  View Answer

Ans: (c)

  • Aman's total trip duration = 15 days.
  • He spent 7 days in Manali.
  • Days spent in Shimla = 15 - 7 = 8 days.
  • The fraction of the trip spent in Shimla = 8 days out of 15 days = 8/15.

So, the correct answer is 8/15.

Q12: A string is 40 m long. A piece measuring 800 cm is cut from it. The remaining piece is then cut into 10 equal pieces. Find the length of each piece.
(a) 320 cm
(b) 350 cm
(c) 400 cm
(d) 410 cm

Maths Olympiad Previous Year Paper -1 | Mathematics Olympiad Class 4  View Answer

Ans: (a)

  • First, convert the total length of the string from meters to centimeters: 
    40 m = 4000 cm.
  • Next, subtract the length of the piece cut from the string: 
    4000 cm - 800 cm = 3200 cm remaining.
  • Now, divide the remaining length by the number of equal pieces: 
    3200 cm ÷ 10 = 320 cm.
  • Thus, the length of each piece is 320 cm.

Q13: Priya had 500 stickers. After giving 150 stickers to her brother, what fraction of the total stickers remains with her?
(a) 5/7
(b) 3/10
(c) 7/10
(d) 7/9

Maths Olympiad Previous Year Paper -1 | Mathematics Olympiad Class 4  View Answer

Ans: (c)

  • Initial number of stickers: Priya had 500 stickers.
  • Stickers given away: She gave away 150 stickers.
  • Remaining stickers: 500150 = 350 stickers500 - 150 = 350 \text{ stickers} stickers
  • Fraction of stickers left: 350/500
  • Simplifying the fraction:Maths Olympiad Previous Year Paper -1 | Mathematics Olympiad Class 4

Thus, the fraction of stickers left is 7/10.

Q14: In January, 4105 children went to the zoo, and in February, 2534 children visited. What is the total number of children who visited the zoo in these two months?
(a) 6548
(b) 6639
(c) 6670
(d) 6234

Maths Olympiad Previous Year Paper -1 | Mathematics Olympiad Class 4  View Answer

Ans: (b)

  • Add the number of children from both months:
    Children in January: 4105
    Children in February: 2534
  • Calculate the total: 4105 + 2534 = 6639

Thus, the total number of children who visited the zoo in January and February is 6639.

Q15: Preeti purchased a piece of cloth that has four equal sides. What shape could this cloth be?
(a) Square
(b) Rectangle
(c) Triangle
(d) None of these

Maths Olympiad Previous Year Paper -1 | Mathematics Olympiad Class 4  View Answer

Ans: (a)

  • The cloth has four equal sides, which means it is a square.
  • A rectangle has opposite sides that are equal, but not all four sides are equal.
  • A triangle has only three sides, so it cannot be the shape of the cloth.

Therefore, the correct shape of the cloth is a square.

Q16: Shreya purchased 86 kg 475 g of sugar, while Puneet acquired 79 kg 825 g of sugar. Who purchased a smaller amount of sugar and by what margin?
(a) Shreya, 6 kg 650 g
(b) Puneet, 6 kg 650 g
(c) Shreya, 7 kg 350 g
(d) Puneet, 7 kg 350 g

Maths Olympiad Previous Year Paper -1 | Mathematics Olympiad Class 4  View Answer

Ans: (b)

  • To determine who bought less sugar, we need to compare the total amounts.
  • Shreya's sugar: 86 kg 475 g = 86475 g
  • Puneet's sugar: 79 kg 825 g = 79825 g
  • Puneet bought less sugar. The difference is 86475 g - 79825 g = 6650 g, which is 6 kg 650 g.

Q17: In which of the following options is 7 not in the hundreds place?
(a) 2790
(b) 3578
(c) 4789
(d) 5785

Maths Olympiad Previous Year Paper -1 | Mathematics Olympiad Class 4  View Answer

Ans: (b)
The hundreds place is the third digit from the right in a number.

  • In 2790, the hundreds place is 2.
  • In 3578, the hundreds place is 5, so 7 is not in the hundreds place.
  • In 4789, the hundreds place is 4.
  • In 5785, the hundreds place is 5.

Thus, the only option where 7 is not in the hundreds place is 3578.

Q18: A city has a population of 92582. Round off the population to the nearest hundreds.
(a) 92500
(b) 92600
(c) 93500
(d) 92580

Maths Olympiad Previous Year Paper -1 | Mathematics Olympiad Class 4  View Answer

Ans: (b)
To round 92582 to the nearest hundred:

  • Look at the tens digit (which is 8).
  • Since 8 is 5 or more, we round the hundreds digit 5 up to 6.
  • Therefore, 92582 rounds up to 92600.

The correct rounded number is 92600.

Q19: Kanika has 4 photo albums. In each album, there are 10 pages. If there are 5 photos on each page, then how many total photos are there in all albums?
(a) 200
(b) 150
(c) 100
(d) 180

Maths Olympiad Previous Year Paper -1 | Mathematics Olympiad Class 4  View Answer

Ans: (a)

  • To find the total number of photos, first calculate the total number of pages across all albums: 
    4 albums × 10 pages = 40 pages.
  • Next, determine the total number of photos by multiplying the total pages by the number of photos per page: 
    40 pages × 5 photos = 200 photos.
  • Thus, the total number of photos in all albums is 200.

Q20: Which Roman numeral is greatest?  
(a) DCLX 
(b) CDXL
