After 24 hours, only 0.125 g out of the initial quantity of 1g of a radioisotope remains behind. what is half-life period?

If 75% quantity of a radioactive isotope disintegrates in 2 hour , its half-life would be :

After two hours 1//6 th of the initial amount of a certain radioactive isotope remains undecayed. The half life of the isotope is :

After 1 hour, 1/8 of the initial mass of a certain radio active isotope remains undecayed. The half-life of the isotope is
