Solution
common explanation: Similarly calculating for each state, we get:
| City | Total | A | B | C |
| Varanasi | 12600 | 4480 | 6720 | 1400 |
| Jaipur | 16200 | 10500 | 3000 | 2700 |
| Bhilwara | 7200 | 1600 | 4000 | 1600 |
| Surat | 7950 | 1908 | 4452 | 1590 |
| Ajmer | 7260 | 1320 | 4620 | 1320 |
Q1. Correct Option: D
From common explanation, we have
Reqd % = 1320/4000 x 100 = 33%
Q2. Correct Option: C
From common explanation, we have
Reqd. average = (4452 + 4620) / 2 = 4536
Q3. Correct Option: A
From common explanation, we have Required difference = (4480 + 6720) – (1600 + 4000) = 5600
Q4. Correct Option: A
From common explanation, we have
Required ratio = (1320 + 1590) : (3000 + 2700) = 97 : 190
Q5. Correct Option: E
From common explanation,
we have Masks receive by A from Jaipur, Bhilwara and Surat = 10500 + 1600 + 1908 = 14008
Masks received by B from Varanasi, Surat and Ajmer = 6720 + 4452 + 4620 = 15792
Required difference = 15792 – 14008 = 1784
