Correct Answer: Rs.156.25
Explanation:
Present worth = 169/(1+4/100)^n = 156.25
Correct Answer: 1300
Correct Answer: 9.6%
Correct Answer: 16000
Correct Answer: 6.3 yrs
Explanation:
P = Rs. 900, R = 3 ½ % = 7/2 %, T = 2 years.
Therefore,
S.I. = PTR/100
S.I. = Rs. (900 x 7/2 x 2/100) = Rs. 63
Now, P = Rs. 200, S.I. = Rs. 63, R = 5 %
Time = ((100 x 63) / (200 x 5) ) years = 6.3 years.
Correct Answer: 48.75
Explanation:
I=
Correct Answer: 5years
Explanation:
I=prt
Correct Answer: Rs. 2424
Explanation:
Now, the principal amount P = Rs. 1,45,440
Rate of interest R = 20%/annum
Now monthly income I = PTR/100 = 1,45,440 x 20 x 1/100 x 12
= 2908800/1200
= Rs. 2424.
Hence, her monthly income = Rs. 2424.
Correct Answer: 6
Explanation:
Let rate = R% and time = R years.
Then, (1200 x R x R) / 100 = 432
=> R = 6.
Correct Answer: 4 : 5
Explanation:
Let x be the investment of Lasya in 5% and y be in 4%
x(5)(n)/100 = y(4)(n)/100
=> x/y = 4/5
x : y = 4 : 5
