Question

if you copy the formula =B4*$D9 from cell B5 to cell B8, what will the formula be in cell B8

Answer 1

if we copy the formula =B4*$D9 from cell B5 to cell B8,

Then the formula cell B8  = B7*$D12

B5 to B8 - three rows increased , column remain same

so  in B4 also three rows increase and become B7 as Column remain same

$D Means  column will remain constant . rows increase 3 so from $D9 to $D12

But if we copy the formula =B4*D$9 from cell B5 to cell B8,

Then the formula cell B8  = B7*D$9

in B4 also three rows increase and become B7 as Column remain same

column will remain constant  as column has not changed rows increase 3 but $ sign make it inconstant so no change in rows so D$9 will remain D$9
