A. 100%
B. 200%
C. 300%
D. 400%
A. 600
B. 620
C. 500
D. 520
E. None of these
Explanation:
Let the number of children in the school be x. Since each child gets 2 bananas, total number of bananas = 2x.
2x/(x – 360) = 2 + 2(extra)
=> 2x – 720 = x => x = 720.
A. 8: 1
B. 2√2 : 1
C. 2 : 1
D. None of these
Explanation:
Volumes be 8×3 and x3
2x and x respectively
Therefore, Ratio of their edges = 2 : 1
A. 120 sq m
B. 300 sq m
C. 150 sq m
D. 480 sq m
1/2 * 15 * 20 = 150
A. Rs.400
B. Rs.500
C. Rs.300
D. Rs.600
E. None of these
Explanation:
Let the amounts to be received by P, Q and R be p, q and r.
p + q + r = 1200
p = 1/2 (q + r) => 2p = q + r
Adding ‘p’ both sides, 3p = p + q + r = 1200
=> p = Rs.400
q = 1/3 (p + r) => 3q = p + r
Adding ‘q’ both sides, 4q = p + q + r = 1200
=> q = Rs.300
r = 1200 – (p + q) => r = Rs.500.
A. Rs. 51.25
B. Rs. 52
C. Rs. 54.25
D. Rs. 60
Explanation:
Sum = (50 * 100) / (2 * 5) = Rs. 500
Amount = [500 * (1 + 5/100)2] = Rs. 551.25
C.I. = (551.25 – 500) = Rs. 51.25.
A. 3:2
B. 1:2
C. 1:5
D. 2:1
p = q+(50/100)q = 1.5q p:q = 1.5q:q = 1.5:1 = 3:2
