Answer: (4)  None of these
Explanation:-
Given- 
principal = Rs.9875,  Time = 2 ears ,   Rate of interest for the first year = 6 %
& Rate of interest for second year = 8 %.

Formula-
Simple Interest = P x R x T/100
Where, P = principal , R = rate, & T = time.

Interest for first years = 9875 x 1 x 6 /100
= Rs.592.50

Interest for second year = (9875 + 592.5) x 1 x 8/100
= 10467.50 x 8 x 1/100
= Rs. 837.40

Then, Total compound interest =  592.50 + 837.40
= Rs.  1429.9

Hence, the simple interest = Rs. 1429.9.
