In a village 15% people died to natural causes and 230 babies were born in that same year, in the next year 35% people from that village migrated to cities. Calculate the number of people who died in the village the previous year, if the present population of the village is 4680? Correct Answer 1230

Let the total population of the village initially was 100x

Now, 15% people died and 230 babies were born

∴ Population of the village now = 85x + 230

35% people from that village migrated to cities

∴ Present population of the village = (65/100) × (85x + 230)

According to the question

⇒ (65/100) × (85x + 230) = 4680 

⇒ 85x + 230 = 4680 × (100/65)

⇒ 85x + 230 = 7200 

⇒ x = 82

∴ Population of the village = 82 × 100 = 8200

Number of people who died in the previous year = (15/100) × 82 = 1230

Delhi, which is one of India's capital an d one of the largest cities in the world, is undergoing severe crisis, due to its high level of urbanization, increasing population and high levels of pollution. Studies have proven that are the biggest factors of pollution used for industrial and domestic use? And due to their use, people here emit large quantities of nitrogen oxides (NOx), ozone (O3), black carbon (BC) and microorganisms (PM).

According to the World Health Organization, 37 cities of India are among 100 worst polluted cities in the world, where PM10 was found to be the highest ever. For the production of onoos, together with sunlight and heat, nitrogen oxides (NOx) and organic compounds (VOCs) are needed simultaneously. Therefore, in the summer months, ozone is produced in large quantities in the cities. Statement: Ozone does not arise more than a boundary on the ground in the summer months in cities. Select the most suitable from the following options A-statement is absolutely true B-statement is probably true C-statement can not be reviewed D-statement is completely false
