Let the amount at 6% be x
Amount at 10% be (10000 ?x)
At 9.2 % interest, SI = 10000 X 9.2 X 1/100 = 920
Amount = 10920
? 6x/100 + (10000 ? x)10/100 = 920
? 6x ? 10x + 100000 = 92000
? 4x = 8000
? x = 2000
Money lent at 10 % = 10000 ? 2000 = 8000
Given Principal amount P = Rs. 10
Time T = 4 months
Rate of interest R = 3 ps
Interest I = PTR/100 = (10 x 4 x 3)/100 = 12/10 = 1.2 paise.
