Work done by (x + 2 ) men in (x - 3) days = (x + 2) (x - 3)
Work done by x men in (x - 2) days = x(x - 2)
? (x + 2) (x - 3) = x(x - 2)
On Solving, we get x = 6
Michel earns Rs. 135 by investing Rs. 1620
To earn Rs. 8 how much he have to invest...?
= (8 x 1620)/135 = Rs. 96
Let investment in each case be Rs. (143 x 117).
Income in 1st case = Rs.
x 143 x 117 = Rs. 1287.
Income in 2nd case = Rs.
x 143 x 117= Rs. 1394.25
Clearly, 9 3/4% stock at 117 is better.
Number of shares = = 540.
Face value = Rs. (540 x 10) = Rs. 5400.
Annual income = = Rs. 648.
Cost of 1 share =
Cost of 96 shares = = Rs. 912.
Cash realised= Rs. (106.25 - 0.25)
= Rs. 106.
