Which Fuel is Cheaper | CodeChef Solution

Hello coders, today we are going to solve Which Fuel is Cheaper CodeChef solution whose Problem code is CHEAPFUEL.

Task

The current price of petrol is X rupees, and the current price of diesel is Y rupees. At the start of each month, the price of petrol increases by A rupees and the price of diesel increases by B rupees.

Chef is curious to know which fuel costs less at the end of the K^th month. If petrol is cheaper than diesel at the end of K^th month, then print PETROL. If diesel is cheaper than petrol at the end of the K^th month, then print DIESEL. If both the fuels have the same price at the end of the K^th month, then print SAME PRICE.

Input Format

• The first line of input contains a single integer T, denoting the number of test cases. The description of T test cases follows.
• Each test case consists of a single line of input, containing five space-separated integers X, Y, A, B, K.

Output Format

For each test case,

• Print PETROL if petrol is cheaper than diesel.
• Print DIESEL if diesel is cheaper than petrol.
• Print SAME PRlCE otherwise.

Note: The output is case-insensitive. You can print each character in either lower-case or upper-case.

Constraints

• 1 ≤ T ≤ 1000
• 1 ≤ K ≤ 1000
• 0 ≤ X, Y, A, B ≤ 1000

Sample Output 1

SAME PRICE
DIESEL
SAME PRICE

Explanation 1

Test case 1:

Initially, the price of petrol is 1 rupee and the price of diesel is 1 rupee. Since A = 1 and B = 1, the prices of both petrol and diesel increase by 1 rupee at the start of every month. So, at the start of the first month, the price of petrol becomes 1 + 1 = 2 rupees and the price of diesel becomes 1 + 1 = 2 rupees. By the end of the first month, the price of petrol and diesel are both 2 rupees and hence they both have the same price.

Test case 2:

Initially, the price of petrol is 2 rupees and the price of diesel is 1 rupee. Since A = 2 and B = 1, the price of petrol increases by 2 rupee and the price of diesel increases by 1 rupee at the start of every month. It follows that at the start of the first month, the price of petrol becomes 2 + 2 = 4 rupees and the price of diesel becomes 1 + 1 = 2 rupees. And by the start of the second month, the price of petrol becomes 4 + 2 = 6 rupees and the price of diesel becomes 2 + 1 = 3 rupees. By the end of the second month, the prices of petrol and diesel are 6 rupees and 3 rupees respectively and hence diesel is cheaper than petrol.

Test case 3:

Initially, the price of petrol is 2 rupee and the price of diesel is 2 rupee. Since A = 1 and B = 1, the price of petrol increases by 1 rupee and the price of diesel increases by 1 rupee at the start of every month. It follows that at the start of the first month, the price of petrol becomes 2 + 1 = 3 rupees and the price of diesel becomes 2 + 1 = 3 rupees. And by the start of the second month, the price of petrol becomes 3 + 1 = 4 rupees and the price of diesel becomes 3 + 1 = 4 rupees. By the end of the second month, the prices of petrol and diesel are both 4 rupees and hence both have the same prices.

Python

#Which Fuel is Cheaper | CodeChef Solution
T = int(input())
while T > 0:
    X, Y, A, B, K = map(int, input().split())
    petrol_price = X + (A * K)
    diesel_price = Y + (B * K)
    
    if (petrol_price < diesel_price):
        print("PETROL")
    elif (diesel_price < petrol_price):
        print("DIESEL")
    else:
        print("SAME PRICE")
    
    T = T - 1
