🧠 Set 1
Directions [01 – 05]:
Three countries — Pumpland (P), Xiland (X) and Cheeseland (C) — trade among themselves and with the (other countries in) Rest of World (ROW). All trade volumes are given in IC (international currency). The following terminology is used:
• Trade balance = Exports – Imports
• Total trade = Exports + Imports
• Normalized trade balance = Trade balance / Total trade, expressed in percentage terms
The following information is known.
1. The normalized trade balances of P, X and C are 0%, 10%, and –20%, respectively.
2. 40% of exports of X are to P. 22% of imports of P are from X.
3. 90% of exports of C are to P; 4% are to ROW.
4. 12% of exports of ROW are to X, 40% are to P.
5. The export volumes of P, in IC, to X and C are 600 and 1200, respectively. P is the only country that exports to C.
1. How much is exported from C to X, in IC?
2. How much is exported from P to ROW, in IC?
3. How much is exported from ROW to ROW, in IC?
4. What is the trade balance of ROW?
(a) 0
(b) 200
(c) -200
(d) 100
5. Which among the countries P, X, and C has/have the least total trade?
(a) Only P
(b) Only X
(c) Both X and C

During the last month, the six friends made several calls to each other. Each call was made by one of these six friends to another. The table below summarizes the number of minutes of calls that each of the six made to (outgoing minutes) and received from (incoming minutes) these friends, grouped by the operators. Some of the entries are missing.
Friend | Operator | Outgoing minutes to | Incoming minutes from | ||
Operator Xitel | Operator Yocel | Operator Xitel | Operator Yocel | ||
Anu | Xitel | 100 |

Chetan | Yocel | 50 | 175 | 250 | 150 |
Deepak | Yocel | 100 | 150 | 275 | 100 |
Eshan | Yocel |
| 100 | 100 | 375 |
Faruq | Yocel | 0 |
| 100 | 150 |
It is known that the duration of calls from Faruq to Eshan was 200 minutes.
Also, there were no calls from:
i. Bijay to Eshan,
ii. Chetan to Anu and Chetan to Deepak,
iii. Deepak to Bijay and Deepak to Faruq,
iv. Eshan to Chetan and Eshan to Deepak.
6. What was the duration of calls (in minutes) from Bijay to Anu?
7. What was the total duration of calls (in minutes) made by Anu to friends having mobile numbers from Operator Yocel?
8. What was the total duration of calls (in minutes) made by Faruq to friends having mobile numbers from Operator Yocel?
9. What was the duration of calls (in minutes) from Deepak to Chetan?
(a) 125
(b) 50
(c) 100
(d) 0
