Answers:

1. Answer: (d)

Let the side of square = ‘x’

Area of square = x²

New length of rectangle = 130 x 100

New Breadth of rectangle = 120 x 100

Hence, Area of so formed rectangle = 130/100x 120/100x X² = 156 x²/ 100

Therefore, area of rectangle exceeds the area of square by 56%

2. Answer: (a)

B’s 1 day work = 1 /12

B’s 9 day’s work = 9 /12 =3/4

Remaining work =1- 3 /4=1/ 4

3. Answer: (b)

A can finish this work in 20 /4 days = 5 days
