Question

If a man earns ₹ 805 per week, in how many days he will earn ₹ 1840?

• A. 7 days
• B. 16 days
• C. 19 days
• D. 23 days

Answer 1

The correct option is B

16 days

Number of days $\propto$ Earnings

$\Rightarrow \text{Number of days = k}\times \text{Earnings where k is a constant.}$

That is, $\frac{\text{Number of days}}{\text{Earnings}}=k$

Earning of 1 week (7 days) = ₹805

$\therefore$ $\frac{7}{805}=k---\left(i\right)$

Let $x$ be the number of days required to earn ₹1840.

$\therefore$ $\frac{x}{1840}=k---\left(ii\right)$

Equating (i) and (ii)

We get $\frac{7}{805}=\frac{x}{1840}$

$\Rightarrow x=\frac{1840\times 7}{805}=16$

$\therefore$ Number of days required to earn ₹1840 = 16
