Question

In the figure, there are fifty, 500 rupee notes in the bundle. Volume of the bundle is 98 cm3, length = 14 cm and breadth = 7 cm. The thickness of 1 note is : 1. 1 mm 2. 0.1 mm 3. 2 mm 4. 0.2 mm

KnowledgeBoat · Accepted Answer

Given,

Number of notes = 50

Volume of bundle = 98 cm³

Length (l) = 14 cm

Breadth (b) = 7 cm

Let the thickness of the bundle be h cm.

Calculating the thickness of the bundle,

Volume of cuboid = length × breadth × height

⇒ 98 = 14 × 7 × h

⇒ 98 = 98 × h

⇒ h = $\dfrac{98}{98}$ = 1 cm.

So total thickness of 50 notes = 1 cm.

∴ Thickness of 1 note = $\dfrac{1}{50}$ cm = 0.02 cm.

1 cm = 10 mm

∴ 0.02 cm = 0.02 × 10 = 0.2 mm.

Hence, option 4 is the correct option.
