(a) 100m 
(b) 200m 
(c) 300m 
(d) 400m

Maths Olympiad Model Test Paper - 2 | Math Olympiad for Class 5  View Answer

Ans: (b) 
Distance covered in completing one round  of the field = perimeter of the field.  
∴ Distance covered in 5 rounds  
= 5 × Perimeter  = 5 × 2 (Length + Breadth)  = 10 (2 × Breadth + Breadth) [L = 2 ×B]  = 10 × 3 × Breadth  = 30 × Breadth.  
But, the total distance covered = 3 km  = 3000 metres  
∴ 30 × Breadth = 3000 metres 
⇒ Breadth = 3000/30 metres = 100 metres 
⇒ Length = 2 × 100 m = 200 m  [Length = 2 × Breadth]

Hence, required number of plants that worm destroyed in the whole field is 810 plants.

Everyday Mathematics

Q36: Sonia wants to frame her 7 rectangular pictures, each of length 5 m and breadth 3 m. What length of wood will she need to make the frames?
(a) 115 m
(b) 105 m
(c) 108 m

Maths Olympiad Model Test Paper - 2 | Math Olympiad for Class 5  View Answer

Ans: (a)

  • To find out how many kites are left, we first need to calculate the total number of kites after the shopkeeper bought more.
  • He started with 54120 kites and bought 40105 kites, so the total becomes 54120 + 40105 = 94225 kites.
  • Next, he sold 75325 kites, so we subtract this from the total: 94225 - 75325 = 18900 kites left in the shop.
  • Thus, the correct answer is 17500 kites remaining.

Q44: 905472 books need to be distributed evenly across shelves. If each shelf holds 384 books, how many shelves will be required?
(a) 2216
(b) 2358
(c) 2456
(d) 2410

Maths Olympiad Model Test Paper - 2 | Math Olympiad for Class 5  View Answer

Ans: (b)

  • To find the number of shelves needed, we divide the total number of books, which is 905472, by the number of books per shelf, which is 384.
  • The calculation is 905472 ÷ 384, which equals 2358.
  • This means that 2358 shelves are required to hold all the books.
  • Thus, the correct answer is (b) 2358.

Q46: The product of two numbers is 936. If their  ratio is 13: 18 then the smallest number is  
(a) 39 
(b) 36  
(c) 54 
(d) 26 

Maths Olympiad Model Test Paper - 2 | Math Olympiad for Class 5  View Answer

Ans: (d)
Let 13/18 = x/y (fraction form)
⇒ 13y = 18x  
⇒ y =  18/13 x  
Product of numbers = 936  
x × y = 936  
18/13 x2 =936  
x2 = 936 × 13/18 x 
x2 = 52 × 13  
x = Maths Olympiad Model Test Paper - 2 | Math Olympiad for Class 5
x = 26

Q47: The sum of three numbers is 98. If the ratio of  the first to the second is 2 : 3 and that of the  second to the third is 5 : 8, then the second  number is:  
(a) 20 
(b) 30  
(c) 38 
(d) 48 

Maths Olympiad Model Test Paper - 2 | Math Olympiad for Class 5  View Answer

Ans: (b)
Let A, B and C be the first, second and third  nos. respectively.  
Then, A: B = 2: 3 and B: C = 5: 8  Consider,  
A : B = 2: 3 = 2 × 5: 3 × 5 = 10: 15  and B: C = 5: 8 = 5 × 3 : 8 × 3 = 15: 24  
∴ A : B : C = 10 : 15 : 24  
Let the required number be 10x, 15x and  24x.  
Given, sum of three numbers = 98  Then,  
∴ 10x + 15x + 24x = 98  
⇒ 49x = 98 ⇒ x = 2  
⇒ Second number = 15x = 15 × 2 = 30
