Question

A labourer receives Rs.385 for 7 days as his wages. (I) What will be his wages if he works for 20 days? (ii)How many days should he work to get Rs.550 as wages?

Answer 1

Answer:

1100 rupees

Step-by-step explanation:

I) 7 days =385

20 days = x

7/385=20/x

x=20×385/7

x=20×55=1100

Answer 2

$\huge {\green {\sf {\underline {\underline{Solution}}}:-}}$

Let his wages for 20 days be ₹ x.

If labour works for more days, his wages will be more.

Hence, it is a case of direct variation.

$\frac{7}{385} = \frac{20}{x} \\ or \\ x = \frac{20 \times 385}{7} = 1100$

Hence, his wages for 20 days work will be ₹ 1100.

Alternative Method :

Wages for 7 days = ₹ 385

$Wages \: for \: 1 \: day = ₹ \frac{385}{7} \\ Wages \: for \: 20 \: days \: = ₹ \frac{385}{7} \times 20 = ₹ \: 1100$
