## HackerEarth - Golden rectangles Solution

You have N rectangles. A rectangle is golden if the ratio of its sides is in between [1.6,1.7], both inclusive. Your task is to find the number of golden rectangles.

**Input format**

- First line: Integer N denoting the number of rectangles
- Each of the N following lines: Two integers W, H denoting the width and height of a rectangle

**Output format**

- Print the answer in a single line.

**Constraints**

**1≤N≤105**

1≤W, H≤109

SAMPLE INPUT

```
5
10 1
165 100
180 100
170 100
160 100
```

SAMPLE OUTPUT

`3`

Explanation

There are three golden rectangles: (165, 100), (170, 100), (160, 100).

## Solution in Python

```
n = int(input())
a = [list(map(int,input().split())) for i in range(n)]
print(sum(1 for i in a if max(i)/min(i)>=1.6 and max(i)/min(i)<=1.7))
```

*Additional Info,*

We use max(i)/min(i) so that always the long the longer side gets divided by the smaller side. That is, either (100,120) or (120,100) our division will be 120/100.
