In 2 days Ram and Hari will cut = 12 kg nuts

In 1 day Ram and Hari will cut = 12/2 = 6 kg nuts

In 5 days Ram and Hari will cut = 5×6 = 30 kg nuts.

The residual amount of nuts = (58-30)= 28 kg nuts.

Now,

In 8 days Ram will cut = 28 kg nuts

In 1 day Ram will cut = 28/8 kg nuts

In 1 day Hari will cut = (6- 28/8) = 2.5 kg nuts

Hari will cut 2.5 kg nuts in = 1day

Hari will cut 1 kg nuts in = 1/2.5 day

Hari will cut 10 kg nuts in = 10/2.5 day = 4 days (answer)
