Question 5.

Ramya wanted to arrange 90 sweets (of dimensions 1×1) in a box. She has 5 boxes of dimensions 10×9, 9×10, 5×18, 16×5 and 18×5. Among these boxes, in which box can she NOT arrange all the sweets?


  1.    10×9
  2.    16×5
  3.    18×5
  4.    5×18
 Discuss Question
Answer is Option B. -> 16×5
The area occupied byone sweet will be1×1=1 sq units and she has to arrange 90 sweetsin the box.

Minimum space needed by Ramya to arrange all the sweets is 90 sq units.
Except for 16×5 the size of all the boxes is 90 sq units.
16×5=80 sq units so she cannot arrange all the sweetsin this box.

Question 6.

In the set of whole numbers, 1 has a predecessor. State True or False?


  1.    True
  2.    False
 Discuss Question

  2.    Whole Number
  3.    Prime Number
  4.    Composite Number

  2.    4
  3.    3
  4.    9

Question 10. In a hypothetical universe, all the numbers are represented using dots. Each number is represented by that many dots as the value of the number. These dots are then joined by a straight line. The number 2 when represented in this world, would only form a ___.
  1.    Line Segment
  2.    Rectangle
  3.    Triangle
  4.    Point
 Discuss Question
Answer is Option A. -> Line Segment

In this hypothetical universe, each number is represented by dots such that the number of dots in that universe corresponds to the value of the number it represents in this universe.
Hence, to represent two, we use two dots. When we join two dots by a straight line, we get a line segment and nothing else, as shown. In A Hypothetical Universe, All The Numbers Are Represented ....
