If Rs. 10 be allowed as true discount on a bill of Rs. 110 due at the end of a certain time, then the discount allowed on the same sum due at the end of double the time is:

Rs. 20
Rs. 21.81
Rs. 22
Rs. 18.33

Discuss Question

Answer: Option D. -> Rs. 18.33

S.I. on Rs. (110 - 10) for a certain time = Rs. 10.

S.I. on Rs. 100 for double the time = Rs. 20.

T.D. on Rs. 120 = Rs. (120 - 100) = Rs. 20.

T.D. on Rs. 110 = Rs.

20
x 110

= Rs. 18.33
120

Question 692.

Rs. 20 is the true discount on Rs. 260 due after a certain time. What will be the true discount on the same sum due after half of the former time, the rate of interest being the same?

Rs. 10
Rs. 10.40
Rs. 15.20
Rs. 13

Discuss Question

Answer: Option B. -> Rs. 10.40

S.I. on Rs. (260 - 20) for a given time = Rs. 20.

S.I. on Rs. 240 for half the time = Rs. 10.

T.D. on Rs. 250 = Rs. 10.

T.D. on Rs. 260 = Rs.

10
x 260

= Rs. 10.40
250

Question 693.

The interest on Rs. 750 for 2 years is the same as the true discount on Rs. 960 due 2 years hence. If the rate of interest is the same in both cases, it is:

12%
14%
15%
16 2 % 3

Discuss Question

Answer: Option B. -> 14%

S.I. on Rs. 750 = T.D. on Rs. 960.

This means P.W. of Rs. 960 due 2 years hence is Rs. 750.

T.D. = Rs. (960 - 750) = Rs. 210.

Thus, S.I. on R.s 750 for 2 years is Rs. 210.

Rate =

100 x 210
%
= 14%
750 x 2

Question 694.

The simple interest and the true discount on a certain sum for a given time and at a given rate are Rs. 85 and Rs. 80 respectively. The sum is:

Rs. 1800
Rs. 1450
Rs. 1360
Rs. 6800

Discuss Question

Answer: Option C. -> Rs. 1360

Sum =
S.I. x T.D.
=
85 x 80
= Rs. 1360.
(S.I.) - (T.D.)
(85 - 80)

If the true discount on s sum due 2 years hence at 14% per annum be Rs. 168, the sum due is:

Rs. 768
Rs. 968
Rs. 1960

Discuss Question

Answer: Option A. -> Rs. 768

P.W. =
100 x T.D.
=
100 x 168
= 600.
R x T
14 x 2

Sum = (P.W. + T.D.) = Rs. (600 + 168) = Rs. 768.

Question 696.

The present worth of Rs. 1404 due in two equal half-yearly installments at 8% per annum simple interest is:

Rs. 1325
Rs. 1300
Rs. 1350
Rs. 1500

Discuss Question

Answer: Option A. -> Rs. 1325

Required sum
= P.W. of Rs. 702 due 6 months + P.W. of Rs. 702 due 1 year hence
= Rs.

The Present Worth Of Rs. 1404 Due In Two Equal Half-yearly I...

100 x 702

100 + (8 x 1)

100 + 8 x

= Rs. (675 + 650)
= Rs. 1325.
