Total Questions: 25

1. How many squares are there in the given figure? [RPF S.I. 24/12/2018 (Morning)]

Correct Answer: (b) 14
Solution:Tricks for finding squares :- in this types of question firstly calculate no. of rows and columns and then apply
[ C ₙ × R ₙ + C ₙ - ₙ × R ₙ - ₙ + ………. Cₙ - ₙ × Rₙ -ₙ ]
In this figure rows = 3 and column = 3
so squares = 3 × 3 + 2 × 2 +1 × 1 = 14

2. How many straight lines are there in the given picture? [RPF S.I. 05/01/2019 (Morning)]

Correct Answer: (b) 10
Solution:In this figure :-
Horizontal lines = 0
Vertical lines = 2
Slant lines = 8
So total straight lines = 0 + 2 + 8 = 10

3. How many simple lines are there in the given image? [RPF S.I. 06/01/2019 (Morning)]

Correct Answer: (c) 9
Solution:

In this figure :-
Horizontal lines = 3
Vertical lines = 2
Slant lines = 4
Total line = 9

4. How many right angled triangles can be made from the given image? [RPF S.I. 06/01/2019 (Morning)]

Correct Answer: (b) 4
Solution:

Here right angle triangles are :-
(dab), (dcb), (edg), (efg)
So, total right angle triangle =4

5. How straight lines are there in the given figure? [RPF S.I. 10/01/2019 (Morning)]

Correct Answer: (c) 7
Solution:

In this figure
Horizontal line : - 1
Slant lines :- 6
Total number of lines = 6 + 1 = 7

6. How many squares are in the given picture? [RPF S.I. 10/01/2019 (Morning)]
