Default Answer for renal absorption

Answer is D. Just subtracting the amount excreted from the filtered load.
Amt absorbed = Filtered load - Amt excreted
= GFR x Plasma concn - Urinne flow rate x Urine concn
(GFR= 100ml/min = 100x1440 /1000 =144 L/day)

Amt absorbed = 144L/dayx140meq/l - 1.44L/dayx100meq/l
= 20016 meq/day
