Read the following information carefully and answer the questions given below.
The information is about the total number of orders delivered by Zomato and Swiggy in three different cities. The average number of orders delivered by Zomato in all three cities is 43 1/3. The total number of orders delivered by Swiggy in A and Zomato in B is in the ratio of 5:3, respectively. The number of orders delivered by Swiggy in C is 20 more than the orders delivered by Zomato in B. The number of orders delivered by Zomato in A and Swiggy in B is the same. The number of orders delivered by Zomato in C is 20% of the number of orders delivered by Swiggy in A. The total number of orders delivered by Zomato and Swiggy together in A is 150.
Q119. The total number of orders delivered by Zomato in A is how many more or less than the total number of orders delivered by Swiggy in C.

Correct answer: A
Caselet-based data interpretation problems state several relationships in words. The standard method is to translate each relationship into an algebraic equation, introduce a single common variable using any given ratio to cut down the number of unknowns, and then solve the resulting system of linear equations simultaneously. Once the unknowns are known, cross-verify every original relationship before reporting the final requested value.
Step 1: Since Swiggy's city-A orders and Zomato's city-B orders are in the ratio 5:3, let Zomato B = 3k and Swiggy A = 5k for a single variable k.
Step 2: Zomato's city-C orders are 20% of Swiggy's city-A orders, so Zomato C = 0.2 x 5k = k.
Step 3: Swiggy's city-C orders are 20 more than Zomato's city-B orders, so Swiggy C = 3k + 20.
Step 4: Zomato's city-A orders equal Swiggy's city-B orders; call this common value m, so Zomato A = Swiggy B = m.
Step 5: The combined Zomato-and-Swiggy total for city A is 150, giving m + 5k = 150.
Step 6: The average Zomato orders across the three cities is 43 1/3, so the citywide Zomato total is 3 x 43 1/3 = 130, giving Zomato A + Zomato B + Zomato C = m + 3k + k = 130, i.e. m + 4k = 130.
Step 7: Subtracting the second equation from the first isolates k: (m + 5k) - (m + 4k) = 150 - 130, so k = 20.
Step 8: Substituting k = 20 back gives m = 130 - 4(20) = 50, so Zomato A = 50, and Swiggy C = 3(20) + 20 = 80.
Step 9: The required difference is Swiggy C - Zomato A = 80 - 50 = 30, so Zomato A's orders are 30 fewer than Swiggy C's orders.
Cross-check: Substituting k = 20 and m = 50 back into every stated relationship confirms consistency: Swiggy A = 100 and Zomato B = 60 keep the ratio at 100:60 = 5:3; Zomato C = 20 is exactly 20% of Swiggy A (100); Swiggy C = 80 is exactly 20 more than Zomato B (60); Zomato A (50) equals Swiggy B (50); the city-A total 100 + 50 = 150 checks out; and the citywide Zomato total 50 + 60 + 20 = 130 gives the stated average of 130 / 3 = 43 1/3. Every constraint holds.
Result: Zomato's city-A orders are 30 less than Swiggy's city-C orders -- the difference is 30.
