Correct Answer - Option 2 : Quantity - I < Quantity - II

Quantity – I

GIVEN:

Let y = 125487 x 59248 x 26527

RULES USED:

⇒ Divisibility of 11 = Difference of alternate sum must be zero or eleven.

CALCULATION:

⇒ Remainder = (125487 x 59248 x 26527)

⇒ Remainder = (1 x 2 x 6)

⇒ Remainder = 12/11

⇒ Remainder = 1

Quantity – II

GIVEN:

⇒ Let Y = 134641 + 4654165 + 905287802 

CONCEPT USED:

1. 4even digit = Unit digit = 6

2. 4odd digit = Unit digit = 4

CALCULATION:

⇒ Unit digit of 134641 = 4

⇒ Unit digit of 4654165 = 4

⇒ Unit digit of 905287802 = (82) = 4

⇒ Adding all = 4 + 4 + 4 = 12

⇒ Unit digit = 2
