Question

what is 20% of 40% of 60% of 200?​

Answer 1

Answer:

To Find:

• 20% of 40% of 60% of 200.

____________...

Procedure:-

$\tt{ \frac{20}{100} \times \frac{40}{100} </p><p>\times \frac{60}{100} \times 200}$

(As per the question)

$\tt{={\cancel{\frac{20}{100} }} \times {\cancel{ \frac{40}{100} }}</p><p>\times {\cancel{\frac{60}{100}}} \times 200}$

(Cancelled some numbers. Fractions are cancelled including 200)

$\tt{= 1.2 \times 4 \times 2}$

(After the cancellation)

$\tt{= \frac{12}{10} \times 4 \times 2}$

(Converted 1.2 into it's fractional form)

$\tt{= \frac {96}{10}}$

(After the Multiplication of the numbers above)

$\boxed{\tt\green{=9.6}}$

(Converted to Decimal Form)

(ANSWER)

____________...

ᴛʜᴇᴀssᴀssɪɴ's BRAIN BOOSTER:-

• $% = \frac {1}{100}}$ "Per" "Cent" where cent stands for century.
• (As we know, $of$ stand for $\times$. We will use this Basicó Konceptó for taking out the solution.)

Answer 2

Answer:

☆ 9.6 or $\huge{\sf {\frac{</strong><strong>9</strong><strong>6</strong><strong>}{</strong><strong>1</strong><strong>0</strong><strong>}}}$ ☆

To Find:

• 20% of 40% of 60% of 200

Solution:

$\small\implies{\sf }$ $\huge{\sf {\frac{<strong>20</strong>}{<strong>100</strong>}}}$ x $\huge{\sf {\frac{<strong>4</strong><strong>0</strong>}{<strong>1</strong><strong>0</strong><strong>0</strong>}}}$ x $\huge{\sf {\frac{<strong>6</strong><strong>0</strong>}{<strong>1</strong><strong>0</strong><strong>0</strong>}}}$ x 200

$\small\implies{\sf }$ $\huge{\sf {\frac{<strong>1</strong>}{<strong>5</strong>}}}$ x 4 x 6 x 2 { After cancelling numbers from both sides }

$\small\implies{\sf }$ $\huge{\sf {\frac{<strong>4</strong><strong>8</strong>}{<strong>5</strong>}}}$

$\small\implies{\sf }$ 9.6 ( Decimal Form )

★ In fractional form 9.6 will be ★

→ $\huge{\sf {\frac{</strong><strong>9</strong><strong>6</strong><strong>}{</strong><strong>1</strong><strong>0</strong><strong>}}}$
