31. (C) First convert from English to Mathematics
32. (B) The article was sold after 25% discount. Hence, the given price Rs.360 is 75% of the actual price. So,
33. (C) We can calculate the height of the parallelogram (the dotted line) by using Pythagoras formula, (Hypotenuses)2 = (Perpendicular)2 + (Base)2
52 = (Height)2 + 32 ∵Perpendicular of Triangle = Height of Parallelogram
(Height)2 = 16
Height = 4
Now, Area of Parallelogram = base × height
= 3×4
= 12 cm2
34. (D)
n  books → r  rupees
m  books → x  rupees
By cross multiplication, we have
nx=mr
x=\frac{mr}{n}
35. (A) Let n  be the common factor. So,
8n-3n = 25  ⇒ 5n=25  ⇒ n=5 . Hence,
8n=8(5)=40  and 3n=3(5)=15 . Thus, the two numbers are: 40 and 15.
