1. 1
Reqd avg marks = (40 + 32.5 + 17.5 + 42.5 + 35)/5 thousand
= 16.5 * 1000/5 = 33500

2. 1
Reqd pecentage = (42.5 * 1000)/(17.5 * 1000) * 100%
= 243% approx

3. 1
Required ratio = (17.5 + 42.5)thousand : (40 + 42.5 + 35) thousands
= 60 : 117.5
= 20 : 39.16
= 20 : 39

4. 2
Reqd Ratio = 32500 : 40000

5. 4
Reqd percentage = (35000 * 100)/(40 + 32.5 + 17.5 + 42.5 + 35) * 1000 * 100%
= 35000/1675% = 21% approx
