SBI lent 1 lakh to farmer Kishan Singh at 6% per annum, at simple interest for a period of 10 years. Meanwhile, the bank offered a discount in the rate of interest, according to the Govt. policy for farmers. Thus, the rate of interest is decreased to 4% p.a. In this way, Kishan Singh had to pay a total amount 1.48 lakh. After how many years did Kishan Singh got the discount in the rate of interest?
