A man lent 60000 Rs. partly at 5% and the rest at 4% simple interest. If the total annual interest is 2560 Rs. the money lent at 4% was :

[A]30000

[B]40000

[C]44000

[D]45000

**44000**

Let the amount lent at 4% be x

∴ Amount lent at 5% = (60000 – x)

According to the question,

Hence option [C] is correct answer.
