A sum becomes 3 times in 5 year at a certain rate of interest. Find the time in which the same amount will be five times at the same rate of interest?

Correct

Explanation:
T=5, SI = 3P-P =2P
2P = P*R*5/100
R = 40%
For another time
SI = 5P-P =4P
4P = P*40*T/100
T = 10 years

Incorrect

Explanation:
T=5, SI = 3P-P =2P
2P = P*R*5/100
R = 40%
For another time
SI = 5P-P =4P
4P = P*40*T/100
T = 10 years

Explanation :
Total Balls = 12
other than blue 8c3 / 12c3 = 14/55
probability = 1-14/55 = 41/55

Incorrect

Explanation :
Total Balls = 12
other than blue 8c3 / 12c3 = 14/55
probability = 1-14/55 = 41/55

Circumference of a circle A is 22/7 times perimeter of a square. Area of the square is 1764 cm². What is the area of another circle B whose diameter is half the radius of the circle A(in cm²)?

Correct

Explanation :
Area = 1764 cm²
a = 42 cm
Perimeter of Square = 4 * 42
Circumference of a Circle = 4 * 42 * 22/7
2πr = 4 * 6 * 22
r = 24 * 22 * 7 / 2 * 22 = 84 cm
Radius of Circle B = 84/4 = 21 cm
Area of Circle = πr² = 22/7 * 21 * 21 = 1386 cm²

Incorrect

Explanation :
Area = 1764 cm²
a = 42 cm
Perimeter of Square = 4 * 42
Circumference of a Circle = 4 * 42 * 22/7
2πr = 4 * 6 * 22
r = 24 * 22 * 7 / 2 * 22 = 84 cm
Radius of Circle B = 84/4 = 21 cm
Area of Circle = πr² = 22/7 * 21 * 21 = 1386 cm²

Two pipes A and B can fill a tank in 12 hours and 4 hours respectively. If they are opened on alternate hours and if pipe A is opened first, in how many hours will the tank be full?

Correct

Explanation :
Pipe A can fill = 1/12
Pipe B can fill = 1/4
For every two hour, 1/12 + 1/4 = 1/3 Part filled
Total = 6 hours

Incorrect

Explanation :
Pipe A can fill = 1/12
Pipe B can fill = 1/4
For every two hour, 1/12 + 1/4 = 1/3 Part filled
Total = 6 hours
