Answer & Explanation

Answers:

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
