The correct options are
B Fraction of slices eaten by Abdul < Fraction of slices eaten by Bheem
C Fraction of slices eaten by Abdul > Fraction of slices eaten by Chris
D Fraction of slices eaten by Bheem > Fraction of slices eaten by Chris
Given,
Abdul eats 6 slices out of an 8 slice pizza, so Abdul's fraction = 68
Bheem eats 7 slices out of an 8 slice pizza, so Bheem's fraction = 78
Chris's eats 5 slices out of an 8 slice pizza, so Chris's fraction = 58
Therefore, the fractions we need to compare are 68, 78 and 58.
They are like fractions, hence, we can compare the numerators, i.e., 5 < 6 < 7.
[Lesser the numerator, lesser the fraction]
⇒ 58 < 68 < 78
Hence, Chris's fraction < Abdul's fraction < Bheem's fraction
Hence, (b), (c) and (d) options are true.
