Read Solution (Total 3)
-
- let investment is x... den remaining investment is (9800-x)
x*9/75= (9800-x)*10/80
x=4800
9800-x=5000 - 11 years agoHelpfull: Yes(4) No(0)
- b. 5000
if invest 5000 for 9% stock at 75
he will earn (5000*9)/75=rs600

- Let the investment in 9% stock be Rs. x.
Then, investment in 10% stock = Rs. (9800 - x).
(9*x)/75=(10*(9800-x))/80
3x/25=(9800-x)/8
x=Rs.5000 - 11 years agoHelpfull: Yes(1) No(0)
