If 20% of a = b, then b% of 20 is the same as :
20% of a = b
=> (20/100) * a = b
b% of 20 =(b/100) x 20 = [(20a/100) / 100] x 20= 4a/100 = 4% of a.

What should come in place of question mark (?) in the following question?
45% of 400+ √? = 56% of 750 - 40% of 350
45/100×400+√?=56/100 ×750 -40/100 ×350
180 + √? = 420 - 140 180 + √? = 280 √? = 280 - 180 √? = 100 ? = 1002 ? = 10000
Each question contains Quantity I and Quantity II. Read the contents clearly and answer your questions accordingly.
Quantity I: if the length of a rectangle is increased by 20% while the breadth of the rectangle is decreased by 10% then find percentage change in area of the rectangle?
Quantity II: if the side of a triangle is increased by 30% while the height of a triangle is decreased by 20% then find the percentage change in area of the triangle?
Quantity I= 20% - 10% - (20*10/100) % = +8%
Quantity II= 30% - 20% - (30*20/100)% = +4%
Hence Quantity I > Quantity II
