A grocer purchased a quantity of bananas at 3 pounds for $0.50 and sold the entire quantity at 4 pounds for $1.00. How many pounds did the grocer purchase if the profit from selling the bananas was $10.00?

(A) 40
(B) 60
(C) 90
(D) 120
(E) 240

Frankly speaking, i couldn't understand the question. Can some body help me out me nailing it down.

1/4 -.5/3 (Note nunites are $/lb)
1/4-1/6
$1/12lb

If profit was 10 then that fraction must be multiplied by 120lb to get 10
Hence D.

OR for Algebra or formula wonks:
Let x = quantity

x/4(selling price per lb) - x/6 (cost price per lb) = profit of 10

X=120

i got confused with pounds and considered pounds as GBP currency. So got lost in curreny cinversion of pounds and dolar. Now i realise my mistake. I wish i had read the question properly.
