Solving both the equations, we get

y > x - The upstream speed and downstream speed of a boat is 32 km/hr and 40 km/hr resp. Find the time taken by the boat to travel a distance of 240 km upstream when the speed of the stream is 50% more than its usual speed?
3 hours6 hours9 hours5 hours8 hoursOption E

Speed of boatman in still water = (32+40)/2 = 36 km/hr.

Speed of stream = (40-32)/2 = 4 km/hr.

New upstream speed = 36 – 1.5*4 = 30 km/hr.

Required time = 240/30 = 8 hours - A and B together can do a piece of work in 12 days. A,B and C together can do the same work in 8 days. In how many days can C alone can do the same piece of work?
26 days24 days25 days20 days28 daysOption B

Total work = 24 units

A and B can do work in one day = 24/12 = 2 units

A, B and C together in one day = 24/8 = 3 units

work done by C alone in one day = 3-2 = 1 unit

Time taken by C alone to complete the work = 24/1 = 24 days - Train A of length 240 m can cross a train B of length 460 m (stationary) in 35 seconds. Find the time taken by both trains to cross each other while moving opposite direction, if train B is moving at a speed 25% less than speed of train A.

25 seconds10 seconds20 seconds15 seconds18 secondsOption C

Let the speed of train A be x m/s.

(240+460)/x = 35

=>x = 20 m/s

Speed of train B = 20*0.75 = 15 m/s

Required time = (240+460)/(20+15) = 20 seconds - Mrs. Sharma invests 15% of her monthly salary, i.e., Rs. 4428 in Mutual Funds. Later she invests 18% of her monthly salary on Pension Policies also she invests another 9% of her salary on Insurance Policies. What is the total monthly amount invested by Mrs. Sharma?

1632918520145801239813125Option D

15% → 4428

1% → 4428/15

( 15 + 18 + 9) = 42% → 4428

15 × 42 → Rs. 12398.4 == 12398 - A trader sells two bullocks for Rs. 8,400 each, neither losing nor gaining in total. If he sold one of the bullocks at a gain of 20%, what is the loss of other sold ?
17(3/7)%13(1/3)%12(3/4)%14(2/7)%11(2/5)%Option D

S.P. of two bullock = 8400 + 8400 = Rs. 16800

CP of first bullock = 100/120*8400 = 7000

CP of second bullock =16800 – 7000

Required % loss = [9800-8400]/9800*100 = 14(2/7)% - The average weight of a class of (x+5) students is 48 kg. If the weight of a student whose weight is 70 kg is excluded, find the average weight of the class decreases by 0.5 kg. Find the value of x.
3060405080Option C

Total weight = (x+5)

48(x+5) – 70 = (48 -0.5)*(x+5-1)

=>x = 40 - Out of his total income, Mr. Kapoor spends 20% on house rent and 70% of the rest on house hold expenses. If he saves Rs 1,800 what is his total income (in rupees)?

Rs.6600Rs.7000Rs.8800Rs.7500Rs.8100Option D

Saving % = 100 – (20 + 56) = 24%

24% = 1800

100% = 1800/24*100 = Rs.7500 - A hemispherical bowl of internal diameter 54 cm contains a liquid. The liquid is to be filled in cylindrical bottles of radius 3 cm and height 9 cm. How many bottles are required to empty the bowl?
180162125170154Option B

Volume of hemi-sphere = 2/3*pi*27*27*27 cm^3

Volume of cylindrical bottle = pi*3*3*9

Required no. of bottles = 162 bottles {Divide hemisphere volume to the cylinder} - A can do a piece of work in 8 days which B can destroy in 3 days. A has worked for 6 days, during the last 2 days of which B has been destroying. How many days must A now work alone to complete the work?
9(1/7) days8(1/4) days7(1/3) days5(1/2) days6(1/5) daysOption C

In 6 days part of the work done by A = 6/8 = ¾

During 2 days, part of the work destroyed by B = 2/3

work done = ¾ – 2/3 = 1/12

Remaining work = 1 – 1/12

Required no. of days = 11/12 × 8 = 7(1/3) days - Two trains, A and B, start from stations X and Y towards each other, they take 4 hours 48 minutes and 3 hours 20 minutes to reach Y and X respectively after they meet if train A is moving at 45 km/hr., find the speed of the train B.

S2/S1 = (24/5)^1/2/(10/3)^1/2 = (36)^1/2/(25)^1/2 = 6/5

Thanks for making me to acquire new tips about pcs. I also hold the belief that certain of the best ways to help keep your laptop computer in prime condition is a hard plastic case, or shell, that suits over the top of the computer. These kind of protective gear are usually model precise since they are made to fit perfectly in the natural outer shell. You can buy these directly from the seller, or through third party places if they are for your mobile computer, however not every laptop may have a cover on the market. Yet again, thanks for your tips.

Thanks for your valuable post. As time passes, I have come to be able to understand that the particular symptoms of mesothelioma are caused by a build up connected fluid regarding the lining in the lung and the breasts cavity. The disease may start in the chest location and get distributed to other areas of the body. Other symptoms of pleural mesothelioma include losing weight, severe respiration trouble, a fever, difficulty taking in food, and bloating of the face and neck areas. It must be noted that some people having the disease never experience just about any serious symptoms at all.
