A. 83 1/3
B. 16 2/3
C. 90
D. 60
p = 6q.
Thus, q is less than p by 5q
q is less than p by (5q/6q x 100)% = 83 1/3 %
A. 50
B. 36
C. 24
D. 12
Explanation:
HCF of 408, 468, 516 = 12

Explanation:
Let the number off boys in the group originally be x.
Total weight of the boys = 30x
After the boy weighing 35 kg joins the group, total weight of boys = 30x + 35
So 30x + 35 + 31(x + 1) = > x = 4
A. 27.5%
B. 37.5%
C. 47.5%
D. 57.5%
Explanation:
100 * 100 = 10000
110 * 125 = 13750
———–
3750
10000 —— 3750
100 ——- ? => 37.5%
A. 1020
B. 1026
C. 1030
D. 1022
Explanation:
Lowest 4-digit number is 1000.
LCM of 3, 4 and 5 is 60.
Dividing 1000 by 60, we get the remainder 40. Thus, the lowest 4-digit number that exactly divisible by 3, 4 and 5 is 1000 + (60 – 40) = 1020.
Now, add the remainder 2 that’s required. Thus, the answer is 1022.
A. 18
B. 13
C. 15
D. 20
Explanation:
(60/100) * 50 – (40/100) * 30
30 – 12 = 18
A. 2:7
B. 5:2
C. 7:2
D. Data inadequate
E. None of these
Explanation:
Let C.P. = Rs. 5x and S.P. = Rs. 7x.
Then, Gain = Rs. 2x
Required ratio = 2x : 5x = 2:5
