Q19. The sequence of folding a piece of paper and how the folded paper has been cut is shown in the following figures. How would this paper look when unfolded?  Solution: Option – (c)

Q20. The ratio of the present ages of Samdish and Manoj is 7 : 8. If the difference between their ages is 8 years, what will be Samdish’s age after 7 years?

a) 56
b) 64
c) 71
d) 57

Solution: Option – (c)
Samdish’s age : Manoj’s age = 7 : 8
Since difference between their ages is 8 years, so multiplying both the numbers by 8, we get –

7 x 8 = 56
8 x 8 = 64

Therefore, Samdish’s age after 7 years: 64 + 7 = 71 years.

Solution: Option – (c); 46 + 57 – 37 = 66

(a); 56 – 47 + 54 = 63

(b); 78 + 38 – 45 = 71

(d); 54 – 76 + 78 = 56

Q22. How many triangles are there in the given figure? a) 22
