CORRECTED QUESTION

If a man earns  ₹800 per week in how many days he will earn ₹4800​ ?

SOLUTION

Money earned by a man in a week = ₹800.

$\sf Weeks\: taken \; to \;earn \: Rs4800 = \dfrac{4800}{Money \: earned\: in \:one \:week}$

$\implies \sf Weeks\: taken \; to \;earn \: Rs4800 = \dfrac{4800}{800}$

$\implies$ Weeks taken  to earn  Rs4800 = 6 weeks

We know that ,

1 week = 7 days

$\implies$ Days taken  to earn  Rs4800  = Weeks taken  to earn  Rs4800 × 7

$\implies$ Days taken  to earn  Rs4800 = 6 × 7

$\implies$ Days taken  to earn  Rs4800 = 42.

Answer 2

Given

• A man earns Rs 800 /- per week

To find

• In how many number of days he will earn Rs 4800 /-

Solution

1 week = 7 days

• 800 - 7
• 4800 - x

Direct proportion is applicable here, since more the days, more is the money earned.

• 800 × x = 7 × 4800
• 800x = 33600
• x = 33600/800
• x = 42

Hence, the men earns Rs 4800 /- in 42 days.
