A.4 hours
B.8 hours
C.12 hours
D.15 hours
E.None of these
Answers :
1) Answer: D
Distance travelled by Q = Y km
Distance travelled by ship by person Q = 60 * 3.75 = 225 km
Y * 15/100 = 225
=> Y = 1500 km
Distance travelled by train by person Q = 1500 * 20/100 = 300km
Distance travelled by Bus by person Q = 1500 * 10/100 = 150km
Distance travelled by Car by person Q = 1500 * 25/100 = 375km
Average distance = (300 + 150 + 375)/3 = 275km
2) Answer: B
Speed of car = 120/100 * 40 = 48kmph
Required time = 300/40 – 300/48 = 1.25 hours
3) Answer: B
From I => Time taken by person P by Bus = (20% of 1200)/60 = 4 hours ≠ 6 hours
This statement is not true.
From II => Time taken by person Q by Flight = (30% of 1500)/50 = 9 hours
This statement is true.
From III => Time taken by person P by bus and car together = (20% of 1200)/60 + (40% of 1200)/60 = 12 hours
This statement is true.
4) Answer: C
Total distance travelled by person Q = Y km
Distance travelled by person Q by flight = 50 * 9 = 450km
Y * 30/100 = 450 => Y = 1500km
5) Answer: C
Total distance travelled by P = X km
25/100 * X = 300 => X = 1200km
Time taken by P to travel by train and Car = (1200 * 20)/(60 * 100) + (1200 * 40)/(60 * 100)
= 4 + 8 = 12 hours
