Alpha decay or α-decay is a type of radioactive decay in which an atomic nucleus emits an alpha particle (helium nucleus) and thereby transforms or `decays` into an atom with a mass number that is reduced by four and an atomic number that is reduced by two.In beta minus (β−) decay, a neutron is converted to a proton and the process creates an electron and an electron antineutrino; while in beta plus (β+) decay, a proton is converted to a neutron and the process creates a positron and an electron neutrino. β+ decay is also known as positron emission.

In alpha decay atomic number decreases by 2 while atomic mass decreses by 4.

But in beta decay atmic number increases by 1 and atomic mass remains constant.

Now
To solve any question first of all check for atomic mass.
By this you can check for alpha decay and then proceed for beta decays.

Atomic mass deceased by 32 hence alpha decay = 32/4 = 8

Now
Atomic numbwr should be 92 - 16 = 76

But final atomic number = 82
Hence increment in atomic number = 6
Hence 6 beta decay
