CityTotalABC
Varanasi12600448067201400
Jaipur162001050030002700
Bhilwara7200160040001600
Surat7950190844521590
Ajmer7260132046201320

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
