3
Find the operator
In the given expression, ‘8 @ 7 – 15 < 4 × 2 × 5’ which operator cannot be used in place of ‘@’,
such that the condition remains valid?
such that the condition remains valid?
4
Passengers on a bus
A bus has 40 seats, and some seats are already occupied, with one passenger in each seat.
- At the first stop, 5 passengers get off and 8 passengers get in
- At the second stop, 2 passengers get off and 4 passengers get in
- At the third stop, exactly half of the passengers get off
After this, half of the bus seats are occupied.
Which of the following expressions represents the number of passengers on the bus at the beginning?
5
Find the least possible value of n
The following expression has a whole number ‘n’. If a blank can either take ‘×4’ or ‘-12’, what is
the least possible value of ‘n’?
the least possible value of ‘n’?
Expression: (n ____ ____ ) ____ = 96
6
Interchange the operators
Which operators should be interchanged to get the minimum value of the given expression?
8 × 4 + 2 – 1
7
Crack the number code
In certain code, 1 is coded as 2, 3 is coded as 10, 5 is coded as 26.
In the same way, 4 is coded as A and 6 is coded as B.
If C is the sum of A and B, which of the following is correct regarding C?
In the same way, 4 is coded as A and 6 is coded as B.
If C is the sum of A and B, which of the following is correct regarding C?
8
Swap the mathematical operators
In the following expression, each ball with a mathematical operator is swapped with the ball
immediately to its left, to form a new arithmetic expression. What will be the value of NEW
EXPRESSION – ORIGINAL EXPRESSION?
immediately to its left, to form a new arithmetic expression. What will be the value of NEW
EXPRESSION – ORIGINAL EXPRESSION?
9
Find the maximum value of the stone
A stone with an initial value of 10 is dropped through one of the holes at the START and moves
in a straight path to reach the END. As it passes each numbered bar along the way, its value
changes according to the operation shown on that bar. What is the maximum value the stone can
have when it reaches the END?
