A. 2/47
B. 3/47
C. 1/48
D. 5/48
Explanation:
HCF of numerators = 1
LCM of denominators = 48
=> 1/48
A. 42.75%
B. 31.25%
C. 35.5%
D. 40.5%
E. None of these
Explanation:
Let the required percentage be x%.
3/20 = x% of 12/25 => 3/20 = x/100 * 12/25
=> 12x = (300 * 25)/20 => x = (25 * 25)/20
=> x = 31.25%.
A. 3/5
B. 5/16
C. 2/9
D. None of these
A. 9
B. 3
C. 0.3
D. 0.03
Explanation:
0.003 * ? * 0.0003 = 0.00000027
3/1000 * ? * 3/10000 = 3/1000 * 3/1000 * 3/100
? = 3/10 = 0.3
A. 21/25
B. 17/25
C. 4/25
D. 8/25
Explanation:
The number of exhaustive events = āµā°Cā = 50.
We have 15 primes from 1 to 50.
Number of favourable cases are 34.
Required probability = 34/50 = 17/25.
A. Rs.1261
B. Rs.9261
C. Rs.9621
D. Rs.9162
Explanation:
A = 8000(21/20)3 = 9261
A. Rs. 3944
B. Rs. 3828
C. Rs. 4176
D. None of these
Let the side of the square plot be a ft.
a2 = 289 => a = 17
Length of the fence = Perimeter of the plot = 4a = 68 ft.
Cost of building the fence = 68 * 58 = Rs. 3944.
