First discount of 20% on 1000=Rs. 200 Second discount = (16% of 1000)+(4% of 84% of 1000) = (160) + ( 4/100 x 84/100 *1000) =Rs. 193.6 Difference=Rs. (200-193.6) =Rs.6.4.

### Answer : A

### Explanation

P.W. = Rs (5125-125) = Rs 5000 S.I. on Rs 5000 for 1/2 year is Rs 125 ∴ R = (100*125)/(5000*1/2)% p.a. = 5% p.a.

### Explanation

P.W. = Rs (2580-180) = Rs. 2400 S.I. on Rs 2400 at 6% p.a. is Rs. 180 ∴ Time = ((100*180))/((2400*6)) years =5/4 years = 1 year 3 months.
