n/2 - 3n/4 + 5n/6 = 21
(6n - 9n + 10n)/12 = 21
7n/12 = 21
7n = 21 x 12
n = (21 x 12)/7
n = 3 x 12
n = 36
Verification : L.H.S = n/2 - 3n/4 + 5n/6
= 36/2 - (3 x 36)/4 + (5 x 36)/6
= 18 - (3 x 9) + (5 x 6)
= 18 - 27 + 30 =
=48 - 27
=21 = R.H.S
HOPING IT WILL BE HELPFUL TO YOU

apurv5:
n=36???
see there ..n°36 and then verify
may be verification wrong
HOPE YOU GETTING IT
not 36 is right answer
I do this question bye bye
OK
then making
6n-9n+10n÷12=21 16n-9n÷12=21
U do this question
