The monthly income of Ram is Rs 40,000. If he paid Rs 8,000 as income tax. Find the rate of income tax.

frosja888 [35]

Hello!

Rate of income tax = Tax paid / Monthly income

⇒ Rate = 8,000 / 40,000

⇒ Rate = 0.2

⇒ Rate = 20%

∴ The rate of income tax is 20%.

Will someone please help me here

frez [133]

Hey!

You have to divide the total amount she has by the surface area.

Surface area = 2(wl+hl+hw)

That gives you:

$(15 + 18 + 30) \times 2 \\ 63 \times 2 = 126$

The surface area is 126 ft. Now divide the total amount she has by the surface area.

$1,134 \div 126 = 9$

<em>That means she can cover 9 boxes</em>

$\framebox{She can cover 9 boxes}$
