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
