A. 12 days
B. 5 days
C. 9 days
D. 6 days
A. A square with an area of 36 sq.cm
B. An Equilateral Triangle with a side of 9 cm
C. A rectangle with 10 cm as length and 40 sq.cm as area
D. A circle with a radius of 4 cm
Explanation:
From Option (A), Area of Square = 36 Sq.cm
Therefore, Side of Square = √36 = 6 cm And
Perimeter of square = 4 × 6 = 24 cm
From option (B), Side of an Equilateral Triangle = 9 cm
Therefore, Perimeter of triangle = 3 × 9 = 27 cm
From Option (C), Length of rectangle , l= 10 cm And
Area of Rectangle = 40 Sq.cm
Let Breadth of Rectangle, b = 40/10 = 4 cm
Therefore, Perimeter of rectangle = 2(10 + 4) = 28 cm
From Option (D), Radius of Circle = 4 cm
Therefore Circumference of circle = 2 × 3.14 × 4 = 25.12 cm
So, Rectangle with 10 cm as length and 40 Sq.cm as an area has a greater perimeter than the rest.

A. 1/25
B. 1/2
C. 4/13
D. 1/10
Explanation:
We have 1, 8, 27 and 64 as perfect cubes from 1 to 100.
Thus, the probability of picking a perfect cube is
4/100 = 1/25.
A. 15
B. 10
C. 8
D. 5
a:b = 3:5 5a = 3b (a+2):(b+2) = 2:3 3(a+2) = 2(b+2) 3a+6 = 2b+4 3*(3b/5) = 2b-2 9b = 10b-10 b =10
A. Rs 4500
B. Rs 5000
C. Rs 5500
D. Rs 6000
Explanation:
Let the money borrowed be Rs x
Interest paid by the money lender = Rs (x × 4/100 × 1) =Rs x/25
Interest received by the money lender
= Rs [x × (1 + 3/100)2 – x]
= Rs(x × 103/100 × 103/100 – x)
Gain = Rs (609x/1000 – x /25)
= Rs 209x/1000 = Rs 609x/10000
Therefore 209x/10000 = 104.50
=> 209x = 1045000
=> x = 5000
Hence money borrowed = Rs 5000
