Correct Answer: (16 + 2/3)%
Explanation:
sum = [(S.I x T.D)/(S.I-T.D)] = Rs. [(375 x 250)/(375-250)] = Rs.750
Rate = (100 x 375)/(750 x 3) = %
Correct Answer: 6000
Explanation:
Let amount be Rs.x then,
[X * R * T] / [100 + (R * T)] = T.D
=> [x * 12 * (3/4)] / [100+(12 * 3/4)] =540
=> x = 6540
Amount = Rs.6540
P.W = Rs.(6540 -540) = Rs.6000
Correct Answer: (6 + 2/3)%
Explanation:
Sum ? Amount
A = (SI x TD)/(SI - TD)
Correct Answer: A gains Rs. 7.34
Explanation:
A has to pay = Present worth of Rs220 due 1yr hence
= Rs.[(220 x 100)/100+(10 x 1)] = Rs.200
A actually pays = Rs.110+PW of Rs.110 due 2 yrs hence
= [110+(110 x 100)] / [100+(10 x 2)] = Rs.192.66
So, A gains Rs. (200-192.66) = Rs.7.34
Correct Answer: 14%
Explanation:
S.I on Rs.750= T.D on Rs. 960
This means P.W of Rs. 960 due 2 years hence is Rs.750
Therefore , T.D= Rs. (960 - 750) = Rs. 210
Thus, S.I on Rs. 750 for 2 years is Rs. 210
Rate =[ (100 x 210) / (750 x 2) ] % = 14%
Correct Answer: 768
Explanation:
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.
Correct Answer: 12%
Explanation:
P.W = Rs.( 2562 - 122) = Rs.2440
S.I on Rs.2440 for 4 months is Rs.122
Rate = (100 x 122)/(2440 x [1/3]) % = 15%
Correct Answer: Rs.1360
Explanation:
Sum = [(S.I x T.D)/(S.I-T.D)] = (85 x 80)/(85-80) = Rs.1360
Correct Answer: Rs.9200
Explanation:
Required Money = P.W of Rs. 10028 due 9 months hence
= Rs.[10028 x 100] / [100+(12 x 9/12)] =Rs.9200
Correct Answer: 50
Explanation:
S.P = P.W of Rs. 2200 due 1yr hence = Rs. [(2200 x 100)/100+(10 x 1)] = Rs.2000
Gain = Rs.(2000-1950) = Rs. 50
