About Salton Sea

• It is a shallow, saline lake located in the lower Colorado Desert, southern California, USA.
• It is a geological depression tucked between mountain ranges and lying below sea level.

Formation:

• The area that is now the lake was formerly a salt-covered sink or depression (a remnant of prehistoric Lake Cahuilla) about 280 feet (85 metres) below sea level until 1905–06, when diversion controls on the Colorado River broke a few miles below the California-Mexico border and floodwaters rushed northward, filling the depression.
• Subsequent deepening of the sink was stopped in 1907, when a line of protective levees was built.
• It is currently 228 feet below sea level.
• It covers an area of 970 square km and includes 130 miles of shoreline.
• It has an average depth of 29.9 feet and, at its deepest, 51 feet.
• Its salinity (some 45 parts per thousand) far exceeds that of seawater.
• The Salton Sea is an important stopping point for migratory waterfowl and serves as critical habitat for birds moving south to Mexico and Central America.

The U.S. Department of Energy recently discovered the world’s largest Lithium reserve beneath California’s Salton Sea.

Let salary = 20,000 + k (experience)
If experience = 2 years
Salary = 50,000
50,000 = 20,000 + k(2)
⇒ k = 15,000
So, for 5 years of experience, salary will be:
20,000 + 15,000(5)
= 95,000

Let total number of children be x.

 Then, x x(1/8)x = (x/2)x 16   ⇔  x = 64

 Number of notebooks =(1/8)x² =(1/8x 64 x 64)= 512

X+x+2+x+4 = 40+(x+x+2+x+4)/3
3x+6 = 40+ (3x+6)/3
(9x+18 – 3x-6)/3= 40
6x + 12 = 120
X = 108/6 = 18
18+2 = 20

Time take for reaching B for ram is T = 5/5 = 1hr
Time taken for reaching B for Shyam is T = 5/10 = 1/2 hr

Its 10 am when ram reaches B and 10: 15 when Shyam reaches B , so they must meet each after 10 and before 10:15 for sure as ram starts back after reaching B

if we see for options 10: 10 am is the only answer

Let the distance be x km. Then,
(Time taken to walls x km) + (Time taken to ride x km) = 23/4 hrs
⇒  (Time taken to walls 2x km) + Time taken to ride 2x km  =  23/2 hrs
but time taken to ride 2x km = 15/4 hrs 
Therefore, Time taken to walk 2x km = (23/2 - 15/4) hrs = 31/4 hrs =7 hr 45 min.

► S.P. of 1 kg of mixture = Rs. 9.24, Gain 10%.

By the rule of allilation, we have:

 Ratio of quantities of 1^st and 2^nd kind = 14 : 6 = 7 : 3.

► Let x kg of sugar of 1^st be mixed with 27 kg of 2^nd kind.

Then, 7 : 3 = x : 27

Alcohol content in the alcohol to be added = 100%
Therefore, the allegation diagram for this problem can be drawn as:

Therefore, ratio of the mixture to alcohol = 70/5 = 14/1
So, alcohol to be added = 100/14

Hence, the answer is "7.14 litres".

Choice B is the correct answer.

Time taken by one tap to fill half of the tank = 3 hrs.
Part filled by the four taps in 1 hour = 
Remaining part = 

 hours i.e, 45 mins.
So, total time taken = 3 hrs. 45 mins.

The absolute value of any number N is always non-negative.
|N| = N, when N > 0 and |N| = -N, when N < 0.
Since N is a negative number, therefore |N| = N is not true.

x = 0, y = ±7
Or x = ±1, y = ±6
Similarly, (±2, ±5)
(±3, ±4), (±4, ±3), (±5, ±2), (±6, ±1), (±7, 0)
(0, ±7) means (0, 7) or (0, -7) → 2 pairs
(±1, ±6) means (1, 6), (1, -6), (-1, 6), (-1, - 6) → 4 pairs
So, total number of possible pairs = 2 + 6 × 4 + 2 = 28

x² - 2x - 3 ≥ 0
(x-3) (x+1) ≥ 0
x belongs to (-∞,-3]∪[3,∞)
Therefore, x belongs to (-1,3)
=> x² - 2x - 3 > 0
x² - 2x - 3< 3x - 3
x² - 5x < 0
x(x-5) < 0
x belongs to (0,5)........(1)
x² - 2x - 3 < 0
x² - 2x - 3 < 3x - 3
x² + x - 6 > 0
(x+3)(x-2) > 0
x belongs to (-∞,-3]∪[2,∞)
x belongs to (2,3)........(2)
Taking intersection of (1) and (2)
we get,
x belongs to (2,5)
 

Only the child of my father means 'Abhisek' himself. This means the girl is the daughter od Abhisek. Hence, Abhisek's wife is the mother of the girl.

Suraj was in the southeast direction with respect to point X.

As 2012 was a leap year, so the number of days in each month from 23rd January, 2011 to 31st July, 2013 is given as follows.
Since 2011 is not a leap year = 365 - 22 = 343 days
Number of days in 2012 = 366 days (leap year)
Number of days in 2013:
January = 31 days
February = 28 days
March = 31 days
April = 30 days
May = 31 days
June = 30 days
July = 31 days
Total number of days in 2013 = 212
Therefore, total number of days from 23rd January, 2011 to 31st July, 2013 = 343 + 366 + 212 = 921
