Answer 1

$\huge{\green{\underline{\underline{Answer:-}}}}$

Given:

Three fifth of pole is painted in red color

Remaining 6m of pole painted in white

To find:

Length of the pole = ?

Solution:

Let x be the total length of pole

Here 3/5 of x is painted in red color and 6 m painted in white color

$\\ \\ \dfrac{3}{5} x + 6 = x \\ \\ \dfrac{3x + 30}{5} = x \\ \\ 3x + 30 = 5x \\ \\30 = 5x - 3x$

$\\ \\ 30 = 2x \\ \\ \dfrac{30}{2} = x \\ \\ x = 15 \\ \\ length \: of \: pole \: is \: 15 \: m$

Required answer:

Thus, length of pole is 15 meter

Knowledge booster:

• Fraction doesn't indicate the real length. We have to find the fraction of a number to get real length
• In exams highlight the main answer as it helps in perfection of sums
