In the recent, climate conference in New York, out of 700 men, 500 women, 800 children present inside the building premises, `20%` of the men, `40% ` of the women and `10%` of the children were Indians. Find the percentage of people who were not Indian?

Answer

To find the percentage of people who were not Indian at the climate conference, we can follow these steps:

### Step 1: Calculate the total number of people present
- **Total men** = 700
- **Total women** = 500
- **Total children** = 800

**Total people** = Total men + Total women + Total children
**Total people** = 700 + 500 + 800 = 2000

### Step 2: Calculate the number of Indians among men, women, and children
- **Indians among men**: 20% of 700
= (20/100) * 700
= 140

- **Indians among women**: 40% of 500
= (40/100) * 500
= 200

- **Indians among children**: 10% of 800
= (10/100) * 800
= 80

### Step 3: Calculate the total number of Indians
**Total Indians** = Indians among men + Indians among women + Indians among children
**Total Indians** = 140 + 200 + 80 = 420

### Step 4: Calculate the number of non-Indians
**Total non-Indians** = Total people - Total Indians
**Total non-Indians** = 2000 - 420 = 1580

### Step 5: Calculate the percentage of non-Indians
**Percentage of non-Indians** = (Total non-Indians / Total people) * 100
**Percentage of non-Indians** = (1580 / 2000) * 100
**Percentage of non-Indians** = 79%

### Final Answer
The percentage of people who were not Indian is **79%**.
