Explanation:
1/x – 1/20 = -1/24
x = 120
120 * 4 = 480
A. 2:5
B. 4:5
C. 6:7
D. 3:5
Explanation:
Let the third number be x.
Then 1st number = 120% of x = (120/100 × x) = 6x/5
2nd number = 150 % of x = (150/100 × x) = 3x/2
Ratio of these numbers = 6x/5 : 3x/2 = 12: 15 = 4 : 5
A. 1/4
B. 1/2
C. 3/4
D. 3/5
The number of exhaustive outcomes is 36.
Let E be the event of getting an even number on one die and an odd number on the other. Let the event of getting either both even or both odd then = 18/36 = 1/2
P(E) = 1 – 1/2 = 1/2.
A. 40
B. 60
C. 240
D. 250
Explanation:
Let S.P = Rs. 100
Then, C.P = Rs. 40
Required Percent = (100/40 × 100) % = 250 %
A. 140
B. 156
C. 175

Given that the area of the square = 1225 sq.units
=> Side of square = √1225 = 35 units
The radius of the circle = side of the square = 35 units Length of the rectangle = 2/5 * 35 = 14 units
Given that breadth = 10 units
Area of the rectangle = lb = 14 * 10 = 140 sq.units
