Question No 1

The ages of C and D are in 6/11 and E is 6 years younger than D. If the sum of ages is 134, then what is the age of D?

Select the correct answer


Solution!
Given that
C/D = 6/11
C = (6/11)D ...(1)

and
C+D+E = 134

As E is 6 years younger from D so we can put D-6 instead of D
C+D+D-6 = 134
C+2D = 140
Put value of C from equation(1)
(6/11)D+2D = 140
6D+22D = 140
28D = 1540
D = 55

Hence D is 55 years old..

A father is 3 years older than 3 times the age of his son. If the sum of their ages is 31 years, how old was father 3 years ago?

Select the correct answer


Solution!
Let present age of son is x and present age of father is y.

Given that
y = 3x+3 ...(1)

and
x+y = 31
x = 31-y

Put value of x in equation(1)
y = 3(31-y)+3
y = 93-3y+3
4y = 96
y = 24

Three years ago
y = 24-3
y = 21

Hence father was 21 years old 3 years ago..

Question No 13

A boatman goes 2 km against the current of the stream in 1 hour and goes 1 km along the current in 10 minutes. How long will it take to go 5 km in stationary water?

Select the correct answer


Solution!
Rate downstream = (1/10) * 60 km/hr = 6 km/hr

Rate upstream = 2 km/hr

Speed in still water = (1/2)(6 + 2) km/hr = 4 km/hr

Hence, Required time = 5/4 hrs = 1 hr 15 min..

Question No 14

A train travelling at the speed of 10m/s can cross a bridge in 23 seconds. If length of the train is 120 meters. What is length of the bridge?

Select the correct answer


Solution!
Speed = v = 10m/s
Time = t = 23s
Length of train = L1 = 120m
Length of bridge = L2 = ?

t = (L1+L2)/v
By putting values
23 = (120+L2)/10
L2 = 230 - 120 = 110m

Hence bridge is 110m long..

Question No 15

A can do a piece of work in 4 hours; B and C together can do it in 3 hours,while A and C together can do it in 2 hours.How long will B alone take to do it?

Select the correct answer


Solution!
A's 1 hour's work = 1/4

(B + C)'s 1 hour's work = 1/3

(A + C)'s 1 hour's work = 1/2

(A + B + C)'s 1 hour's work = (1/4 + 1/3) = 7/12

B's 1 hour's work = (7/12 - 1/2) = 1/12

Hence, B alone will take 12 hours to do the work..
