Q1. Select the pair which has same type of relationship like Barometer : Pressure
A Force : KG
B Richter Scale : Heat
C Weighing Scale : Meter
D Thermometer : Temperature
EXPLANATION
D
From the information given in the question, we can infer that we need to check for such a relationship where the instrument is being used to measure the physical quantity. ( since Barometer is being used to measure atmospheric pressure.)
In option A, the unit of force is given as kg, which is not a correct relationship. Richter scale is used to measure the strength of earthquakes, but in the option, it is linked to heat. Therefore, option B is not correct.
The weighing scale measures the weight of an object, whose unit is Kg. Hence, this is wrong. The thermometer
measures temperature, which is the correct relationship.
The correct option is D.
Q2. Find the odd one among the following :
A 143
B 168
C 225
D 195
EXPLANATION
.C
The four numbers are 143, 168, 195, and 225
The difference, (168-143) = 25, (195-168) = 27, hence the next difference should be 29. Hence the next number
should be (195+29) = 224.
Therefore, 225 is the odd number here. The correct option is C
Q3. If% means ‘is less than’, $ means’ is greater than and# means ‘is equal to’ and given that a%b, c#d and c$b then which is true?
A a > b
B a < c
C c > d > a
D d < b
EXPLANATION
B
a%b means a is less than b. c#d means c is equal to d, and c$b means c is greater than b.
