PW of Rs.12,880 due 8 months hence
= Rs. [12880 x 100] / [100+(18 x 8/12)] =Rs.11500
Clearly 12000 in cash is a better offer.
Correct Answer: 1325
Explanation:
Required Sum = PW of Rs.702 due 6 months hence + PW of Rs.702 due 1 year hence
= Rs.[ (100 x 702) / (100+(8 x 1/2)) ] + [ (100 x 702) / (100+(8 x 1)) ]
= Rs.1325
Correct Answer: 1764
Correct Answer: 15%
Explanation:

Rate = [100 x 122] / [2440 x (1/3)] =15%
Correct Answer: 6000

Let amount be Rs. x.
Then, [X * R * T] / [100+(R * T)]
x= Rs.6540

Explanation:
We know that,
P.W = 100×T.D/R×T
= 100×168/14×2
P.W = 600.
Now, required Sum = (P.W. + T.D.)
= Rs. (600 + 168)
= Rs. 768.
Correct Answer: 5
Explanation:
loss = C.P - S.P = 490 - 465.50 =24.50
loss % = (loss x 100)/C.P = (24.50 x 100)/490 = 5%
