The Taj Mahal took 22 years to complete, with construction starting in 1631-1632 and finishing in 1653. The main mausoleum was completed earlier (1643-1648), but the entire complex including gardens and outlying buildings took 22 years.

The construction cost of the Taj Mahal was approximately 32 crore rupees in the 17th century's currency valuation. Over 20,000 workers were employed, and materials were brought from all over India and Central Asia.

Approximately 20,000 workers were employed in the construction of the Taj Mahal, including craftsmen, artisans, and laborers from across India, Central Asia, and the Middle East. This included over 1,000 elephants for transporting materials.

The Taj Mahal was commissioned by Shah Jahan as a mausoleum for his beloved wife Mumtaz Mahal, who died during childbirth in 1631. It stands as an eternal symbol of love and is one of the most recognizable monuments to romantic love in the world.

The adult human body is approximately 60-70% water, with the exact percentage varying by body composition and gender. The brain and heart are about 73% water, while bones are about 31% water. The overall average for adults is commonly cited as 60-70%.

At birth, an infant's body is approximately 75-80% water by weight, which is significantly higher than adults. This percentage decreases to adult levels (60-70%) as the child grows and body composition changes, including increased fat and muscle development.

Thirst is triggered when the body has lost approximately 1-2% of its total water content. By this point, mild dehydration has already begun, which is why it's recommended to drink water regularly throughout the day rather than waiting until you feel thirsty.

Water intoxication (hyponatremia) occurs when excessive water consumption dilutes sodium levels in the blood to dangerous levels. This can cause cells to swell, leading to potentially life-threatening complications including brain swelling. It's most common in endurance athletes and people participating in water drinking contests.

Pure water has a pH of 7 because it is neutral, meaning the concentration of hydrogen ions equals the concentration of hydroxide ions. The pH scale ranges from 0-14, with 7 being the neutral point. Pure water contains only H2O molecules with equal concentrations of H+ and OH- ions from autoionization.

The pattern decreases by 2, 4, 6, 8. Starting from 35: 35-2=33, 33-4=29, 29-6=23, 23-8=15. The next decrease should be 10, so 15-10=5. This is a simple arithmetic progression where the difference increases by 2 each time.

The pattern increases by consecutive odd numbers: +7, +9, +11, +13, +15. Starting from 8: 8+7=15, 15+9=24, 24+11=35, 35+13=48, 48+15=63. The next increment should be 17, so 63+17=80. This follows n²-1 pattern where n starts from 3.

The first differences are +2, +6, +14, +30. The second differences (differences of differences) are +4, +8, +16, which double each time. The next second difference should be 32, so the next first difference is 30+32=62. Therefore, 54+62=116. This is a geometric progression in the second-order differences.

The pattern alternates between subtracting 2 and adding 1: 19-2=17, 17+1=18, 18-2=16. The next operation should be +1, so 16+1=17. This is a simple alternating pattern between two operations.

The pattern alternates between dividing by 2 and adding 4: 96÷2=48, 48+4=52, 52÷2=26, 26+4=30. The next operation should be ÷2, so 30÷2=15. This is a mixed operation series with alternating division and addition.

The pattern is: subtract 10, add 12, subtract 13, add 15, subtract 16, add 18. The subtractions increase by 3 each time (10, 13, 16, 19). The additions increase by 3 each time (12, 15, 18). After adding 18 to get 26, the next operation is subtract 19, giving 26-19=7.

The pattern alternates between two interleaved sequences. Odd positions: 1, 2, 3, 4 (increases by 1). Even positions: 7, 6, 5, 4 (decreases by 1). The 7th position should continue the odd position pattern: 4. The sequences are moving toward each other.

The pattern multiplies by consecutive integers starting from 2: 2×2=4, 4×3=12, 12×4=48. The next multiplier should be 5, so 48×5=240. This is a factorial-like progression where each step multiplies by the next integer.

This is a simple arithmetic progression with common difference 11: 12+11=23, 23+11=34, 34+11=45. The next term is 45+11=56. Each term increases by the same amount.

The pattern alternates between multiplying by 5 and subtracting 7: 7×5=35, 35-7=28, 28×5=140, 140-7=133. The next operation should be ×5, so 133×5=665. This is a mixed operation series with alternating multiplication and subtraction.
