Answer 1

Answer:

6561 people.

explanation :

on sunday riya told 3 people

the formulae

on monday each of these 3

people told to 3 more people.

that is, the formulae was told

to a total of (3×3=9) 9 people.

on tuesday these 9 people

told to (9×3=27) 27 people.

notice the pattern?

the pattern is ---> 3¹,3²,3³

⚪on the first day, no.of people

who knew the formulae = 3¹ = 3

⚪on the 2nd day, no.of people

who knew the formulae = 3² = 9

⚪on the 3rd day, no.of people

who knew the formulae = 3³ = 27

so,

the next sunday, that is,

on the 8th day,

3⁸ = 6561 people will know the formulae.
