The given table shows the marks of various students in a class. Study the table and answer the question that follows.

Which two students have the least difference of marks between them?

Correct option is C

Solution:

Sum of marks of A = (48 + 47 + 49 + 46 + 44) = 234

B = 29 + 33 + 22 + 15 + 30 = 129

C = 35 + 36 + 42 + 40 + 29 = 182

D = 46 + 49 + 48 + 48 + 40 = 231

E = 32 + 30 + 25 + 21 + 22 = 130

By options

So, difference of B and C = 182 – 129 = 53

Difference of A and D = 234 – 231= 3

Difference of B and E = 130 – 129 = 1

Difference of E and D = 231 – 130 = 101

Least difference is of B and E = 1
