A. 5 kmph
B. 10 kmph
C. 30 kmph
D. 15 kmph
Explanation:
US = 25
DS = 35
M = (35 – 25)/2 = 5
A. 1
B. 2
C. 4
D. Data Inadequate
A. 2 : 5
B. 1 : 5
C. 3 : 5
D. 4 : 5
The volume of the cone = (1/3)πr2h
Only radius (r) and height (h) are varying.
Hence, (1/3)π may be ignored.
V1/V2 = r12h1/r22h2 => 1/10 = (1)2h1/(2)2h2
=> h1/h2 = 2/5
i.e. h1 : h2 = 2 : 5
A. 18
B. 20
C. 24
D. 30
Explanation:
Average = (10 + 15 + 20 + 25 + 30)/5 = 100/5 = 20
A. 8 cc
B. 16 cc
C. 32 cc
D. 64 cc
6a2 = 24
a = 2 => a3 = 8cc
A. 13 %
B. 11 1/9 %
C. 11.25 %
D. 12 1/9 %
Explanation:
Let the C.P of the article be Rs 1 per gram
C.P of 900gm = Rs 900,
S.P of 1000gm = Rs 1000
Gain % = (100/900 × 100)% = 100/9 % = 11 1/9 %
A. Rs. 40
B. Rs. 50
C. Rs. 60
D. Rs. 70
Explanation:
Let C.P = Rs. X
X + X% of X = 75
X2 + 100 X – 7500 = 0 Or (X+ 150) (X – 50) = 0
X = 50 (neglecting X= – 150)
