86. If a carton contains 8 eggs, how many cartons are will be required to keep 320 eggs?
(a) 30 cartons
(b) 35 cartons
(c) 45 cartons
(d) 40 cartons
Answer:
(d) 40 cartons
Explanation:
To find the total number of cartons, divide the total number of eggs by the capacity of one carton. 320 ÷ 8 = 40.
87. Which among the following 4-digit number will look the same on half a turn?
(a) 7007 (b) 1212 (c) 1100 (d) 1404
Answer:
(c) 1100
(Note: See Explanation)
Explanation:
Mathematically, none of these options perfectly display rotational symmetry of 180 degrees (a half turn). However, test questions like this often mistakenly equate mirror reflection (palindromes like 7007 or 1404) with rotational symmetry. If one were to write “1100” and rotate it 180 degrees, it visually reads as “0011”. Since none match strictly, this question is technically flawed on the exam, but students often incorrectly select the numeric palindromes.
88. A shape that has 6 sides is called?
(a) Rectangle
(b) Square
(c) Pentagon
(d) Hexagon
Answer:
(d) Hexagon
Explanation:
In geometry, a polygon with exactly six straight sides and six angles is called a hexagon.
89. Convert 5 kilogram and 500 grams into grams.
(a) 5500 grams
(b) 5000 grams
(c) 500 grams
(d) 50 grams
Answer:
(a) 5500 grams
Explanation:
1 kilogram equals 1000 grams. Therefore, 5 kilograms is 5000 grams. Adding the extra 500 grams gives a total of 5000 + 500 = 5500 grams.
90. If a person buys 2 kg 500 g of rice and 3 kg 500 g of wheat, calculate total weight.
(a) 5 kg
(b) 6 kg
(c) 7 kg 500 g
(d) 5 kg 500 g
Answer:
(b) 6 kg
Explanation:
Add the kilograms: 2 kg + 3 kg = 5 kg. Add the grams: 500 g + 500 g = 1000 g. Since 1000 g = 1 kg, the total weight is 5 kg + 1 kg = 6 kg.
