Answer :
Let the Arjun carry x no of arrows.
He used x/2 arrows to cut down Bheeshm arrows.
He used 6 arrows to kill the rath driver and another 3 for rath,flag and bow.
He use 4√x +1 arrows to put Bheeshm on arrow bed.
From above the we have
x/2+6+3+4√x+1=x
⇒ x +20 +8√x= 2x
⇒ x-8√x-20=0
⇒ √x(√x-10) + 2(√x-10)=0
⇒ (√x+2)(√x-10)=0
⇒ √x=10 0r x=100 ( neglecting -tive value)
Arjun had 100 arrows.
