CTET Solved Paper - UTET April 2015 Paper2
- Option : C
- Explanation : Option (C) is correct i.e. Given property of whole numbers is known as closure property of addition.
- Option : D
- Explanation : (D) Let the production of Y =100
Then, production of X =120
Production of Z =150
Required ratio of X, Y and X
=X : Y : Z
=120 : 100 : 150
=12 : 10 : 15
114. The mean of the median and mode of the observations 6, 6, 9, 14, 8, 9, 9, 8 is
- Option : C
- Explanation : (C) Arranging the numbers in ascending order, we get 6, 6, 8, 8, 9, 9, 9, 14
As, median is middle number and here 8 and 9 are middle numbers. So median = (8 + 9)/2 = 8.5
Mode is the number that appears the most, which is 9.
So, Mean of median and mode = (8.5 + 9)/2 = 17.5/2 = 8.75
- A
In a triangle, if the angles opposite to two sides have equal measures, then the two sides are equal
- B
In a triangle, if two sides are not equal, then the angles opposite to these two sides do not have equal measures
- C
In a triangle, if its measures of angles opposite to two sides are not equal, then the two sides are not equal
- D
