A man is engaged as a typist for 30 days on the condition that he receives
₹175 for each day he works and has to pay 50 for each day he remains
absent. If he receives ₹4125 in all, for how many days does he remain absent?​

Answer 1

Answer:

175) 4125 ( 23

350

-----------------

625

525

------------------

100

he was absent for 2 days because reminder is 100

(2×50)+(23×175) =4125

Answer 2

Answer:

5 days

Step-by-step explanation:

Earning- x days per ₹175

Spending - y days per -50

Monthly income- ₹4125

1) x+y=30 - number of days

2) 175x-50y=4125 - monthly income

From 1)  we get y=30-x

175x-50(30-x)=4125

225x-1500=4125

225x=5625

x=5625/225

x=25 days

y=30-25=5 days

So the typist was absent for 5 days

Proof:

25*175-5*50=4125
