Question
The latest UN projections suggest that the world’s
population could cross 9 billion by which year?Solution
The latest UN projections suggest that the world’s population could grow to around 8.5 billion in 2030 and 9.7 billion in 2050, before reaching a peak of around 10.4 billion people during the 2080s. The population is expected to remain at that level until 2100.
(2197)1/3 + (18)2 − 121 = ? − 69 × 5
[(15)³ × (8)²] ÷ (90 × 6) = ?²
120% of 400 + ?% of 520 = 1000
15% of 1800 + 22 = ?
20% of 550 × 25% of 80 = ?2 × 22
What will come in the place of question mark (?) in the given expression?
(16 × 22 + 23) ÷ 15 + 24 = ?2 – 16 × 2
- What will come in place of (?) in the given expression.
56% of 250 + 32% of 150 = ? √256 * 4 – 30% of 190 + ? = 110% of 220
- What will come in place of (?), in the given expression.
(5³ + 3²) × 2 = ? If 14 (x - y) = 2744 and 14 (x + y) = 537824, what is the value of x?
