density of iron/density of oak = 8, since mass of iron ball = mass of oak ball,
volume of oak ball = 8 times volume of iron ball, i.e R(oak)^3 = 8 * R(iron)^3.. solving this you would get R(iron) is 4.5cm

ARUN SHARMA or TIME'S QUANT BOOKS?
I have all of the Time's material which i studied last year.
Should I buy Arun Sharma for Quant, is it worth it?( better than Time's Quant). I have already done all the exercises of Time's Quant books last year, and my score was pathetic(i guess due to slow speed), so shoud i redo time's quant or go for Arun Sharma or do both?
Puys , waht do u suggest?
and any opinions on other books of arun sharma (di and VA) ?Thanks
