E. None of these
Explanation:
Let the total number of votes polled in the election be 100k.
Number of valid votes = 100k – 20% (100k) = 80k
Let the number of votes polled in favour of A and B be a and b respectively.
a – b = 15% (100k) => a = b + 15k
=> a + b = b + 15k + b
Now, 2b + 15k = 80k and hence b = 32.5k
It is given that 100k = 8720
32.5k = 32.5k/100k * 8720 = 2834
The number of valid votes polled in favour of B is 2834.
A. 6.24 km
B. 6 km
C. 5.76 km
D. 5.66 km
Explanation:
M = 6
S = 1.2
DS = 7.2
US = 4.8
x/7.2 + x/4.8 = 1
x = 2.88
D = 2.88 * 2 = 5.76
A. Rs. 20
B. Rs. 21.81
C. Rs. 22
D. Rs. 18.33
A. 9:19
B. 19:9
C. 15:28
D. 28:15
Let A1 be the area of flat and A2 be that of the commercial space
Total cost = area * rate
Therefore, cost of flat = A1*4500 ; cost of commercial space = A2*9500
Both the above costs are same
A1*4500 = A2*9500
A1:A2 = 9500:4500 = 19:9
A. 1
B. 2
C. 3
D. 4
E. None of these
Explanation:
Let the two-digit number be 10a + b
a = b + 2 — (1)
10a + b = 7(a + b) => a = 2b
Substituting a = 2b in equation (1), we get
2b = b + 2 => b = 2
Hence the units digit is: 2.
A. 1.4
B. 1.6
C. 1.5
D. 1.2
Explanation:
(180/37 of 14.8) / (17/60.1 of 180.30) = 72/51 = 24/17 = 1.41
