Answer 2

Answer:Three Person Thought Numbers 10,55,22

Step-by-step explanation:

The product of the three numbers should be a composite numbers which can be expressed as a product of 6 primes (need not be distinct but atleast two of the prime are distinct)

As 120=2³*3*5, 120cannot be expressed as product of six prime numbers

As 144=2⁴*3², can be expressed as product of six primes but one has a number that is, not a product of two primes which is not possible

As 12100=2²*5²*11², 12100 can be expressed as the product of six prime and can be thought as (2*5)*(2*11) *(11*2)

Therefore the Numbers those three Persons choosed was 10,55,22
