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
A. 5 hours 50 min
B. 6 hours
C. 6 hours 50 min
D. 12 hours 10 min
Explanation:
Let the speed of motor boat be 36x km/hr and that of current of water be 5x km/hr
Speed downstream = (36x +5x)km/hr = 41x km/hr
Speed upstream = (36 -5x)km/hr = 31x km/hr
Distance covered downstream = (41x × 31/6)km
Distance upstream = [1271x/6 × 1/31x]hrs
= 41/6 hrs = 6hrs 50 min
A. 2000
B. 3000
C. 4000
D. 6000
Explanation:
Let 815 + ? be k
=> 84k/100 – (815 * 84)/100 = 1680
=>84(k/100 – 815/100) = 1680
=> (k – 815)/100 = 20 => k = 2815
k = 815 + ? = 2815 => ? = 2000
A. 25 liters
B. 28 litres
C. 30 liters
D. 35 liters
Explanation:
Total cost price =Rs(40 x 7/2) = Rs.140
Cost per litre =Rs.2,
Total quantity = 140/2 = 70 Litres.
Water to be added =(70-40) =30 Litres.
A. 25000
B. 33000
C. 35000
D. 40000
Explanation:
Let the number of votes enrolled be x
Votes cast = (90/100 × x) = 9x/10
Valid votes = 90% of 9x/10 = (90/100 × 9x/10) = 81x/100
Votes polled by successful candidate
= (54/100 × 81x/100) = 4374x/10000
Votes polled by defeated candidate
= (46/100 × 81x/100) = 3726x/10000
=> 4374x – 3726x = 16200000
=> x = 16200000/648 = 25000
A. 4920 cm2
B. 4727 cm2
C. 9856 cm2
D. 19712 cm2
