1 ton 5-star Inverter ac electricity consumption

If I use it at 29c in daytime for like 8 hours how much units, it will consume.

When I am using like this my compressor getting turned off like after 5 mins.

I don't like much cooling but, in this summer, can't tolerate the much heat also.

What all options I have to operate the ac at low cost.

What happens if I put ac temp as 28c and outside temp is 24c like in nights
