1,40,00,000 Pencils Are Put Up Straight. All The Pencils Are Of Length Range 3 To 6 Inches. 80% Of The Pencils Have Average Of Five Inches. So The Find Out The Total Length Spanned By The Pencils?

Answer»

LENGTH covered by 80% of the PENCILS =80/100 * 14000000 * 5 = 56000000 inches

Minimum length covered by REMAINING 20% of the pencils =20/100 * 14000000 * 3 = 8400000 inches

MAXIMUM length covered by remaining 20% of the pencils =20/100 * 14000000 * 6 = 16800000 inches

Hence, total length spanned by the pencils is (56000000 +8400000) to (56000000 +16800000 )

ie, 64400000 inches to 72800000 inches.
