Verified by Toppr

(i) potatoes sold by merchant $=6kg+541 kg+921 kg+943 kg$

It can be written as

$=(6+21/4+19/2+39/4)$ kg

LCM of 1, 4 and 2 is 4

$=(24+21+38+39)/4$

By further calculation

$=122/4$

$=61/2kg$

$=3021 kg$

(ii) Potatoes left in the sack $=120kg−3021 kg$

It can be written as

$=(120/1−61/2)$ kg

By further calculation

$=(240−61)/2$ kg

So we get

$=179/2kg$

$=8921 kg$
