Question No 1

4 men and 6 women can complete a work in 8 days, while 3 men and 7 women can complete it in 10 days. In how many days will 10 women complete it?

Select the correct answer

Solution!
Let, 1 man's 1 day's work = x
and
1 woman's 1 day's work = y

Then, 4x + 6y = 1/8 nd 3x + 7y = 1/10

Solving the two equations, we get
x = 11/400
y = 1/400

So, One woman's 1 day's work = 1/400

10 women's 1 day's work = (1/400 * 10) = 1/40

Hence, 10 women will complete the work in 40 days..

Question No 15

A train passes a station platform in 36 seconds and a man standing on the platform in 20 seconds. If the speed of the train is 54 km/hr, what is the length of the platform?

Select the correct answer

Solution!
Speed = 54 * (5/18)m/s
= 15 m/s

Length of the train = (15 x 20)m = 300 m

Let the length of the platform be x metres

Then,
(x+300)/36 = 15
x + 300 = 540

Hence, x = 240 m.

Question No 16

A 150m long train is running at the speed of 36km/h. In what time will it pass the 80m long bridge?

Select the correct answer

Solution!
Length of train = L1 = 150m
Speed = v = 36 Km/h = 36*(5/18) = 10 m/s
Length of bridge = L2 = 80m

Time = t = (L1 + L2)/v
t = (150+80)/10 = 23

Hence the train will pass the 80 meter long bridge in 23 seconds..

Question No 17

It was Sunday on Jan 1, 2006.What was the day of the week Jan 1, 2010?

Question No 19

If 1/2 x year ago A was 12 and 1/2 x years from now he will be 2x years old, how old will he be 3x years from now?

Select the correct answer

Solution!
Given that
A-(1/2)x = 12
2A-x = 24 ...(1)
and
A+(1/2)x = 2x
A+(1/2)x-2x = 0
A+(x-4x)/2 = 0
A-(3/2)x = 0
2A-3x = 0 ...(2)
By simultaneously solving equation(1) and (2) we have
x = 12
and
A = 18

Now
3x = 3*12 = 36

After 3x years A will be
18+36 = 54 years old.

= 50/3m/s

Let the length of the platform be x metres

Then, (x+300)/39 = 50/3
3(x + 300) = 1950

Hence, x = 350 m.

(A + B + C)'s 1 day's work = 1/6

(A + B)'s 1 day's work = 1/8

(B + C)'s 1 day's work = 1/12

So, (A + C)'s 1 day's work = (2* 1/6) - (1/8 + 1/12)
= (1/3 - 5/24) = (3/24) = 1/8

So, A and C together will do the work in 8 days..

y-5x = -60 ...(2)

By simultaneously solving equation(1) and equation(2)
y = 40

Hence Tina's present age is 40 years..

Let speed of boat in still water is x.
Speed of water = v = 6 Km/h
As downstream speed is four times the upstream speed so

(x+6) = 4(x-6)
x+6 = 4x-24
30 = 3x
x = 10

Hence speed of boat in still water is 10 Km/h.

Question No 51

X can do a piece of work in 40 days.He works at it for 8 days and then Y finished it in 16 days.How long will they together take to complete the work?

Select the correct answer

Solution!
Work done by X in 8 days = (1/40 * 8)
= 1/5

Remaining work = (1 - 1/5)
4/5

Now, 4/5 work is done by Y in 16 days.

Whole work will be done by Y in (16 * 5/4)
= 20 days

So,
X's 1 day's work = 1/40
Y's 1 day's work = 1/20

(X + Y)'s 1 day's work = (1/40 + 1/20) = 3/40

Hence, X and Y will together complete the work in 40/3 days.
