	A.  Rs.1680
	B.  Rs.1750
	C.  Rs.1840
	D.  Rs.1443.75

Solution

P.W.= Rs = [100 x 2310/100 +(15 x5/2)] = Rs. 1680.

7.	The true discount on Rs. 1760 due after a certain time at 12% per annum is Rs. 160. The time after which it is due iss
	A.  6 months
	B.  8 months
	C.  9 months
	D.  10 months

Solution

P.W = Rs. (1760 -160) = Rs.1600 S.I. on Rs. 1600 at 12% is Rs. 160. Time = (100 x 160/1600 x 12) =5/6 years. =(5/6 x12) months =10 months.

8.	Find the present worth of Rs. 930 due 3 years hence at 8% per annum. Also find the discount?
	A.  Rs.500
	B.  Rs.625
	C.  Rs. 750
	D.  Rs. 890

P.W =100 x Amount/100+(RxT) = Rs[100x930/100+(8x3)] = Rs.(100x930/124) = Rs.750.

9.	A man purchased a cow for Rs. 3000 and sold it the same day for Rs.3600, allowing the buyer a credit of 2 years. If the rate of interest be 10% per annum, then the man has a gain of
	A.  0%
	B.  5%
	C.  7.5%

C.P = Rs. 3000. S.P =Rs[3600x100/100+(10x2)] =3000 So, Gain is 0 %.

10.	If the true discount on s sum due 2 years hence at 14% per annum be Rs. 168, the sum due is
	A.  Rs.768
	B.  Rs.968
	C.  Rs.1960
	D.  Rs.2400

Solution

P.W =100 x T.D/R x T = 100 x 168/14 x 2 = 600. Sum = (P.W + T.D) Rs. (600 + 168) = Rs. 768.
