Answer» 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 |
