# Body Mass Index Codechef Solution Hello Programmers In this post, you will know how to solve the Body Mass Index Codechef Solution.

One more thing to add, don’t directly look for the solutions, first try to solve the problems of Codechef by yourself. If you find any difficulty after trying several times, then you can look for solutions.

### Problem

You are given the height HH (in metres) and mass MM (in kilograms) of Chef. The Body Mass Index (BMI) of a person is computed as MH2MH2. Report the category into which Chef falls, based on his BMI:

• Category 1: Underweight if BMI ≤18≤18
• Category 2: Normal weight if BMI ∈{19∈{19, 2020,……, 24}24}
• Category 3: Overweight if BMI ∈{25∈{25, 2626,……, 29}29}
• Category 4: Obesity if BMI ≥30≥30

### Input:

• The first line of input will contain an integer, TT, which denotes the number of testcases. Then the testcases follow.
• Each testcase contains a single line of input, with two space separated integers, M,HM,H, which denote the mass and height of Chef respectively.

### Output:

For each testcase, output in a single line, 1,2,31,2,3 or 44, based on the category in which Chef falls.

### Constraints

• 1≤T≤2∗1041≤T≤2∗104
• 1≤M≤1041≤M≤104
• 1≤H≤1021≤H≤102
• Its guaranteed that H2H2 divides MM.

```3
72 2
80 2
120 2
```

```1
2
4
```

### Explanation:

Case 1: Since MH2=7222=18MH2=7222=18, therefore person falls in category 11.

Case 2: Since MH2=8022=20MH2=8022=20, therefore person falls in category 22.

Case 3: Since MH2=12022=30MH2=12022=30, therefore person falls in category 44.

### Body Mass Index CodeChef Solution in JAVA

```import java.util.*;
class Codechef
{
public static void main (String[] args) throws java.lang.Exception
{
Scanner sc = new Scanner(System.in);
int T;
T = sc.nextInt();
while(T-->0){
int M=0, H=0;
int BMI=0;
M = sc.nextInt();
H = sc.nextInt();
BMI = M/(H*H);
if(BMI<=18){
System.out.println("1");
}
else if(BMI>18 && BMI<=24){
System.out.println("2");
}
else if(BMI>24 && BMI<=29){
System.out.println("3");
}
else{
System.out.println("4");
}
}
}
}```

### Body Mass Index CodeChef Solutions in CPP

```#include <iostream>
using namespace std;
int main() {
int t;
cin>>t;
while(t--){
int m,h,k;
cin>>m>>h;
k=m/(h*h);
if(k<=18){
cout<<"1\n";
}
else if(k>=19 && k<=24 ){
cout<<"2\n";
}
else if(k>=25 && k<=29){
cout<<"3\n";
}
else if(k>=30){
cout<<"4\n";
}
}
return 0;
}```

### Body Mass Index CodeChef Solutions in Python

```import math
for test in range(int(input())):
weight,height = list(map(int,input().split(" ")))
if ((weight/(height**2)))>=30:
print("4")
elif ((weight/(height**2)))>=25:
print("3")
elif ((weight/(height**2)))>=19:
print("2")
elif ((weight/(height**2)))<=18:
print("1")```
