Answers :

1) Answer: E

Required sum = 1260 + 1450 + 1260 + 2560 + 1920 = 8450

2) Answer: C

Required difference = [(2000 + 2500 + 3000)/3] – [(1260 + 1260 + 1920)/3]

= 2500 – 1480 = 1020

3) Answer: A

Required % = [(740 + 1740)/4000] * 100 = (2480/4000) * 100 = 62%

4) Answer: E

Number of student failed in the exam in,

B = 2500 – 1450 = 1050

C = 3000 – 1260 = 1740

E = 4000 – 1920 = 2080

Required difference = (1050 + 1740 + 2080) – (1260 + 1450 + 1260) = 900

5) Answer: D

Number of student failed in the exam in,

A = 2000 – 1260 = 740

B = 2500 – 1450 = 1050

C = 3000 – 1260 = 1740

D = 3500 – 2560 = 940

E = 4000 – 1920 = 2080

Required average = (740 + 1050 + 1740 + 940 + 2080)/5 = 1310
