A. 8
B. 9
C. 12
D. 16
Explanation:
80% — 12
120% — ?
80/120 * 12 = 8
A. 3.5km/hr
B. 5.75km/hr
C. 6.5km/hr
D. 7km/hr
Explanation:
Speed Downstream = 15.5 km/hr,
speed upstream = 8.5 km/hr
Speed of the stream = ½ (15.5 – 8.5)km = 3.5 km/hr
A. No loss or gain
B. Loss of Rs. 1000
C. Gain of Rs. 1000
D. Gain of Rs. 2000
Explanation:
Loss% = (20/10)2 = (2)2 = 4%
Total S.P = Rs. 24000
Total C.P = Rs. (100/96 × 24000) = Rs. 25000
Loss = Rs. 1000
A. Rs. 600
B. Rs. 700
C. Rs. 800
D. Rs. 685
Explanation:
Original price be Rs. X
C.P = (X – 25% of X) = 3X/4
S.P = (3X/4 + 10% of 3X/4) = 33X/40
33X/40 = 660
=> X = 800
A. 3%
B. 4%
C. 5%
D. 6%
S.I. = Rs. (15500 – 12500) = Rs. 3000.
Rate = ( 100 X 3000/12500 X 4 )% = 6%.
A. 90
B. 270
C. 810
D. 240
Explanation:
16.66% of 33.33% of 66.66% of x = 30
= 1/6 of 1/3 of 2/3 of x = 30
=> (30 * 6 * 3 * 3)/2 => x = 810
A. 651
B. 361
C. 100
D. 95
Explanation:
³√216400 + √280 + √322
= 60 + 16.5 + 18 = 94.5 = 95
