Answer : B
Explanation
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.
Q 6 - The genuine markdown on an aggregate due 8 months consequently at 6% p.a. is Rs 130. The total due is:

Q 8 - A man needs to offer his old bike. He has two clients. One of them needs to pay Rs 12000 in trade and the other out Rs 13500 payable following 8 months. On the off chance that the rate of hobby is 12% for every annum, which alternative is better for the dealer?
Answer : B
Explanation
Cash payment = Rs 12000 P.W. of Rs. 13500 payable after 8 months = Rs ((100*3500))/(100+(12*8/12) ) = Rs ((100*13500))/108=Rs 12500 ∴ Rs 13500 payable after 8 months is a better offer

Answer : C
Explanation
C.P. = Rs 1056 S.P. = P.W. of Rs 1296 due 6 months hence = Rs. (100*1296)/(100+(12*1/2) ) = Rs ((100*1296))/106= 1200 ∴ Profit = Rs (1200-1056) = Rs 144 Gain% = (144/1056*100)% = 13.6%
Q 10 - The basic enthusiasm on Rs 750 for a long time is equivalent to the genuine rebate on Rs 810 for the same time and at the same rate. The rate of interest per annum is:
