Question

plz solve this ......​

Answer 1

Answer:

x=15/0.40×0.08

x=3

Therefore, the answer is 3.

Answer 2

GIVEN:

• (?)/0.08 = 15/0.40

TO FIND:

• The value of unknown quantity (?)

SOLUTION:

Let the unknown quantity be x

$\implies \bf \: \frac{x}{0.08} = \frac{15}{0.40}$

By cross multiplication we get,

$\implies \tt \: x \times 0.40 = 15 \times 0.08 \\ \\ \implies\tt \: 0.40x = 1.2 \\ \\ \implies \tt \: x = \frac{1.2}{0.40} \\ \\ \implies \tt \: x = 3$

Hence the value of x (?) is 3.

Verification:

$\tt \dfrac{x}{0.08} = \dfrac{15}{0.40}$

putting the value of x = 3

so,

LHS

$\tt \dfrac{x}{0.08} = \dfrac{3}{0.08}$

RHS = $\tt \dfrac{15}{0.40}$

both numerator and denominator are divisible by 5,

= $\tt \dfrac{3}{0.08}$

LHS = RHS,
