Answer & Explanation

Answer (1-5):
L = lower limit
U = upper limit
The lower limit and upper limit of marks for students can be calculated for illustration.
1. (b)
Total minimum marks of Pooja = 375
Total maximum marks = 500
Required % = 375/500*100=75%
2. (a)
Subject: Employment Law
L = 2(91) + 3(81) + 2(71) + 1(51) + 1(41) + 1(0) = 182 + 243 + 142 + 51 + 41 + 0 = 659
3. (c)
Vishakha cannot score less than 375.
4. (c)
The upper limit of the marks for all the candidates is less than 450. So, all the candidates must have obtained total marks less than 450.
5. (e)
Divyanshu – [345, 390]
Ritu       – [355, 400]
Divyanshu must score more than 355. He cannot score, 345 or 348 or 350 or 355.
