Actual rate percent = [91/2 / (100 + 0 + 0)] x 100
= 91/2%
Required answer = 96(10 - 3/4 + 1/4) = Rs. 912
Required answer = [(1700 x 425) / 4] x 100
= Rs. 1806.25
7350 = (Amount of stock x 105 + 0) / 100
? Amount of stock = (7350 x 100) / 105 = Rs. 7000
Required answer = [7 / (100 - 5 + 0.25)] x 100 = 7.349
= 7.35% (Approx. )
400 = (Ans / 102) x 10
or Ans = (102 x 400) / 10
? Ans = 102 x 40 = Rs. 4080
Actual rate percent = [91/2 / (100 + 14 + 0)] x 100
= 25/3
= 81/3%
100 = (1800 x 5) / (Ans - 0)
or Ans = (1800 x 5) / 100 = 90
? Required answer = Rs. 90
120 = (3000 x 6) / (Ans - 0)
? Ans = (3000 x 6) / 120 = Rs. 150
96 = (770 x 9/2) / (Ans - 1/4)
or Ans = (770 x 9/2) / (96 + 1/4)
Ans = Rs. 36
Let the investment in 4% stock be Rs. N.
Then, investment in 5% stock = Rs. (2780 - N)
Income from 4% stock = Rs. (4/75) x N
Income from 5% stock = Rs. [(5/80 x (2780 - N)]
? 4N / 75 = (2780 - N) / 16
or N = 1500
So, investment in 5% stock = Rs. (2780 - 1500) = Rs. 1280
