## CAT DILR : 2017 slot 2 questions

### Funky Pizzeria

Funky Pizzeria was required to supply Pizzas to three different parties. The total number of Pizzas it had to deliver was 800. 70% of which was to be delivered to Party 3 and the rest equally divided between Party 1 and Party 2.

Pizzas could be of Thin Crust (T) or Deep Dish (D) variety and come in either Normal Cheese (NC) or Extra Cheese (EC) versions. Hence, there are 4 types of Pizzas: T – NC, T – EC, D-NC, D-EC. Partial information about proportions of T and NC pizzas ordered by the three parties are given below.

Question 4: Suppose that a T-NC pizza cost as much as a D-NC pizza, but 3/5th of the price of a D-EC pizza. A D-EC pizza costs Rs. 50 more than a T-EC pizza, and the latter costs Rs. 500. If 25% of the Normal Cheese pizzas delivered to Party 1 were of Deep Dish variety, what was the total bill for Party 1?

1. Rs.59480
2. Rs.59840
3. Rs.42520
4. Rs.45240

##### Method of solving this Question on CAT DILR

General Solution

First, let us get some simple numbers in place. 70% of 800 people attended Party 3. Or, 560 people attended this party. The remaining 240 were split equally, or 120 each on Party 1 and Party 2.

Now, let us look at these decimals. 0.6 = 3/5; 0.55 = 11/20; 0.3 = 3/10; 0.65 = 13/20;
The best of the fractions is 0.375 which is 3/8; this helps a lot. Now, we know that we are going to fill data in two classifications T or D and NC or EC. So, let us capture data also in these two formats

After we create these two tables, it is just a matter of filling the numbers in.

Once some numbers are present, the rest fill in automatically

Given, 25% of NC pizzas delivered to Party 1 were of Deep Dish variety. So, D-NC = 0.25*16 = 4. T-NC = 16 – 4 = 12. Given, D-EC = Rs. 50 more than TEC.
Given, D-EC = Rs. 50 more than TEC. Cost of TEC = Rs. 500. Hence, DEC = Rs.550.
So, cost of TNC = DNC = * 550 = 3*110 = Rs.330.

No. of TNC + DNC = 16. Cost of NC pizzas = 330*16 = 5280.
No. of T-NC = 12. Hence, T-EC = T – T-NC = 72 – 12 = 60.
Cost of T-EC pizzas = 60*500 = 30,000.

No. of D-NC = 4. Hence, D-EC = D – D-NC = 48 – 4 = 44.
Cost of D-EC pizzas = 44*550 = 24200.

Total cost = Rs. 5280 + Rs. 30000 + Rs. 24200 = Rs. 59480.

The question is "what was the total bill for Party 1?"

##### Hence, the answer is "Rs.59480".

Choice A is the correct answer.
