Answer 1

answer - Which pair of elements has similar properties

a) 13, 31

b) 11,20

c) 12, 10

d) 21, 33

Let see each pair and find what is similar in those

13 , 31 - both are prime numbers and both are also odd numbers so we can say this pair has similar property

12 , 10 - both are even numbers

so we can say this pair has similar property

21 , 33 both are divisible by 3 and both are odd numbers

so we can say this pair has similar property

b) 11,20 - no similar property ( as one number is odd , other is even , one is prime other is non-prime)
