Answer 1

Given data:-

• A man was engaged as typist for the month of march in 2019.
• He was paid Rs, 500 per day.
• Rs 100 per day were deducted for the days he remained absent.
• He received Rs. 8,900 as salary
• for the month.

Solution:-

We know, 31 days in month of march.

—› Total salry of typist without deduction Rs 100 = Rs {31 × 500} = Rs 15500 ....( 1 )

Subtract received salary from ( 1 ) to find amount of deduction

—›Amount of deduction = Rs{15500 - 8900}

—›Amount of deduction = Rs 6600

Now,

—› Day's of absent

= {Amount of deduction}/{Amount of per day earning}

—› Day's of absent = 6600/500

—› Day's of absent = 13.2 days or 13 days (approx)

Now, subtract 13 days from 31 days of march to calculate days of working days of typist .

—› Working days = {31 - 13}day

—› Working days = 18 days

Hence,typist worked for 18 days.

{ Note: option ( d ) is the answer }.

Answer 2

Answer:

We know that there are 31 days in the month of March.

So total salary for 31 days working days without deductions would be---31×500 = 15500 Rs.

Amount of deduction = 15 500 - 8900 =6600

Total deduction for one absent day = 500 +100 = 600

So days of absent =6600/600 = 11

Hence,working days = 31-11=20 days
