A. Rs. 400
B. Rs. 360
C. Rs. 480
D. Rs. 320

Answer: Option A

Explanation:

T.D.
= B.D. x 100
100 + (R x T)
= Rs. 420 x 100
100 + 15 x 1
3
= Rs. 420 x 100
105
= Rs. 400.

A. 3 months
B. 4 months
C. 6 months
D. 8 months

Answer: Option B

Explanation:

S.I. on Rs. 1600 = T.D. on Rs. 1680.

Rs. 1600 is the P.W. of Rs. 1680, i.e., Rs. 80 is on Rs. 1600 at 15%.

Time = 100 x 80 year = 1 year = 4 months.
1600 x 15 3

Answer: Option C

Explanation:

T.D. = B.G. x 100 = Rs. 24 x 100 = Rs. 120.
Rate x Time 10 x 2

P.W. = 100 x T.D. = Rs. 100 x 120 = Rs. 600.
Rate x Time 10 x 2


4. 

The banker's discount on a sum of money for 1 years is Rs. 558 and the true discount on the same sum for 2 years is Rs. 600. The rate percent is:

A. 10%
B. 13%
C. 12%
D. 15%

Answer: Option C

Explanation:

B.D. for years = Rs. 558.
B.D. for 2 years
= Rs. 558 x 2 x 2
3
= Rs. 744

T.D. for 2 years = Rs. 600.

Sum = B.D. x T.D. = Rs. 744 x 600 = Rs. 3100.
B.D. - T.D 144

Thus, Rs. 744 is S.I. on Rs. 3100 for 2 years.

Rate = 100 x 744 % = 12%
3100 x 2

Answer: Option C

Explanation:

T.D. = B.G. x 100 = Rs. 270 x 100 = Rs. 750.
R x T 12 x 3

B.D. = Rs.(750 + 270) = Rs. 1020.
