Question : 16 [SSC CGL Tier-I 2014]
A train leaves a station A at 7 am and reaches another station B at 11 am. Another train leaves B at 8 am and reaches A at 11.30 am. The two trains cross one another at
a) 8:56 am
b) 9:00 am
c) 9:24 am
d) 8:36 am
Answer »Answer: (c)
Let both trains meet after t hours since 7 a.m.
Distance between stations A and B = x Km.
$x/4 × t + x/{7/2} × (t - 1) = x$
[Speed = $\text"Distance"/ \text"Time"$]
$t/4 + {2(t - 1)}/7$ = 1
${7t + 8t - 8}/28$ = 1
15 t - 8 = 28
15 t = 28 + 8 = 36
t = $36/15 = 12/5$ hours
= 2 hours 24 minutes
∴ Required time = 9 :24 a.m.
Question : 17 [SSC Delhi Police S.I.2012]
Points 'A' and 'B' are 70 km apart on a highway. A car starts from 'A' and another from 'B' at the same time. If they travel in the same direction, they meet in 7 hours, but if they travel towards each-other, they meet in one hour. Find the speed of the two cars (in km/hr).
a) 40, 30
b) 30, 50
c) 20, 40
d) 20, 30
Answer »Answer: (a)
Let speed of car starting from A be x kmph
and speed of car starting from B be y kmph
Case I
When cars meet at P,
7x = AP = AB + BP = 70 + 7y
7x - 7y = 70
x - y = 10 ...(i)
Case II
When cars meet at Q,
x + y = 70 ...(ii)
On adding these equations,
x = 40 kmph
Putting the value of x in equation (i),
y = 40 - 10 = 30 kmph
