Options

• 27.33 cm

• 30 cm

• 31.33 cm

• 33.33 cm

Answer 1

In a swimming pool measuring 90 m × 40 m, 150 men take a dip. If the average displacement of water by a man is 8 m3, then rise in water level is 33.33 cm.

Explanation:

Volume of water displaced

= 150 × 8 = 1200 m³

⇒ 90 × 40 × h = 1200

⇒ h = `1200/(90 xx 40)`m = 33.33 cm
