Question
. Which of the following numbers is divisible by
24?Solution
Divisible by 24. =3×8 If the number is divided by 3 and 8 then the number is totally divided by 24. According to the concept, Now we check if the numbers are divisible by 3: 52668= 5+2+6+6+8= 27 [ divisible by 3] 99984 = 9 +9+9+8+4 =39 [divisible by 3] 64760 = 6+4+7+6+0 = 37 [not divisible by 3] 26968 = 2+6+9+6+8 = 31 [not divisible by 3] Now we check if the numbers are divisible by 8: 52668= 668/8 =83(4/8) [not divisible by 8] 99984 = 984/8 = 123 [divisible by 8] 64760 = 760/8 = 95[ divisible by 8] 26968 = 968/8 = 121 [divisible by 8] So, option 1.is right.
