Correct Answer: 15
Explanation:
Sum = [(B.D.xT.D.)/ (B.D.-T.D.)]
= [(B.D.xT.D.)/B.G.]
T.D./B.G. = Sum/ B.D.
=1650/165
=10
Thus, if B.G. is Re 1, T.D. = Rs. 10.
If B.D.is Rs. ll, T.D.=Rs. 10.
If B.D. is Rs. 165, T.D. = Rs. [(10/11)xl65]
=Rs.150
And, B.G. = Rs. (165 - 150) = Rs, 15.
Correct Answer: 5%
Explanation:
Let T.D. be Re. 1.
Then, B.D. = Rs.11/10= Rs. 1.10.
Sum = Rs. (1.10*1)/(1.10-1) = Rs. (110/10)= Rs. 11.
S.I. on Rs. 11 for 2 years is Rs. 1.10
Rate = [(100 x 1.10)/(11 x 2 )]% = 5%.
Correct Answer: 600
Explanation:
T.D = (B.G * 100) / (Rate * Time)
(24*100) / (10 * 2)
= 120.
P.W = (100 *T.D) / (Rate * Time)
= (100 * 120) /(10 * 2)
= 600
Correct Answer: 52.8
Correct Answer: 45000
Correct Answer: 129
Explanation:
B.G. = S.I. on T.D.
= Rs.(120 x 15 x 1/2 x 1/100)
= Rs. 9.
(B.D.) - (T.D.) = Rs. 9.
B.D. = Rs. (120 + 9) = Rs. 129.
Correct Answer: 4 months
Explanation:
S.I. on Rs. 1800 = T.D. on Rs. 1872.
P.W. of Rs. 1872 is Rs. 1800.
Rs. 72 is S.I. on Rs. 1800 at 12%.
Time =[(100 x 72)/ (12x1800)]year
=1/3year = 4 months.
Correct Answer: 50
Explanation:
T.D. =(B.G. x 100)/ (R x T)= Rs. (6 x 100)/( 12 x 1) = Rs. 50.
Correct Answer: 1020
Explanation:
T.D. =(B.G*100)/(R*T)=Rs(270*100)/(12*3) = Rs. 750.
B.D. = Rs.(750 + 270) = Rs. 1020.
