Explanation:

To determine the percentage by which Zomato's orders in City D are more than Swiggy's orders in City B, follow these steps:

- Let's denote the number of orders delivered by Swiggy in City B as `S_B`.

- Denote the number of orders delivered by Zomato in City D as `Z_D`.

- Calculate the percentage increase as \(\frac{Z_D - S_B}{S_B} \times 100\).

Now, let's evaluate the options:

- Option 1: 60%: This implies Zomato's deliveries are 60% more than Swiggy's.

- Option 2: 50%: Suggests half of Swiggy's deliveries are added by Zomato.

- Option 3: 66.66%: Reflects a two-thirds increase over Swiggy's figures.

- Option 4: 33.33%: Reflects a one-third increase.

- Option 5: 40%: Suggests a 40% increase.

Based on calculations (not shown here), if Zomato's orders are indeed 60% more than Swiggy's, then:

- Option 1: 60%
