    Total number of people in 2013 is 1500. Then find the total number of employees who work in end of 2011?

    Solutions

    Total number people who joined all 3 years = 450

    Joined person 2010 + joined person of 2011 + joined person of 2012 = 450

    Ratio between joined person of 2010 and 2011 = 3: 4

    So, 3x + 4x + 100 = 450

    7x = 350, x = 50

    People joined in 2010 and 2011 = 150, 200

    People left in 2010 = ratio of who joined in 2010 and left in 2010 = 3 : 1

    So, (150/3) × 1= 50

    People left in 2011 = 200 × 37.5 % = 75

    Total number of people left the company = 50 + 75 + 25 = 150

    Employees in 2011 end = who works in 2011 end + who joined in 2012 – who left in 2012 = 1500

    x + 100 – 25 = 1500

    x = 1425

    Total number of employees work in 2009 end is 1000. Find the ratio between total number of employees working in 2011 end and total number of people who left the job all 3 years?

    Solutions

    Total number people who joined all 3 years = 450

    Joined person 2010 + joined person of 2011 + joined person of 2012 = 450

    Ratio between joined person of 2010 and 2011 = 3: 4

    So, 3x + 4x + 100 = 450

    7x = 350, x = 50

    People left in 2010 = ratio of who joined in 2010 and left in 2010 = 3 : 1

    So, (150/3) × 1= 50

    People left in 2011 = 200 × 37.5 % = 75

    Total number of people left the company = 50 + 75 + 25 = 150

    Employees working in 2011 end = 1000 + (who joined in 2010 – who left in 2010) + (who joined in 2011 - who left in 2011)

    = 1000 + (150 – 50) + (200 -75)

    = 1225

    Ratio between employee working in 2011 end: who left all 3 years = 1225: 150 = 49: 6

    People left in 2011 = 200 × 37.5 % = 75

    Total number of people left the company = 50 + 75 + 25 = 150

    Employees in 2011 end = 1500 + (200 – 75) = 1625

    Office assistant = 20% of 1625 = 325

    Office assistant salary = 325 × 10000 = 3250000

    Officers = 40% 1625 = 650

    Officers salary = 650 × 15000 = 975000

    Manager salary = 650 × 25000 = 1625000

    Total salary expense = 3250000 + 9750000 + 16250000 = Rs 29250000

    A chair making company x, and their employees are A, B, C, and D. and their efficiency in the ratio 7: 8: 10: 6. They start to make 775 chairs. The company x can fixed manufacturing cost Rs 240 for one chair with 20% profit. Production cost and employee’s salary per chair is in the ratio 5: 3. Then find person C’s total salary?

    Solutions

    MRP without profit = (240/100) × 80 = 200

    Production cost and salary = 5: 3 = 200/8 * 5: 200/8 * 3 = 125: 75

    Total chair manufactured by C = (775/31) × 10 = 250

    Salary of C = 250 × 75 = Rs 18750

    A boat goes 40 km upstream and comes back in 25 hrs. If still water speed is 5 km/hr. Find the difference of time if boat goes 48km downstream and 24 km upstream?

    Solutions

    40/(5 + x) + 40/(5 – x) = 25

    x = 3

    So 24/(5 – 3) – 48/( 5 + 3) = 12 - 6 = 6 hrs

    Train A and train B travels from Delhi to Lucknow and Lucknow to Delhi respectively. Distance between these 2 places is 450 km. speed of two trains is 50km/hr and 80km/hr respectively. Train B started after 2 hrs of train A. train A increasing its speed by 10km every 2 hrs and train B reduced 10 km/hr by every hour. Find the time taken by A to meet B.

    Solutions

    Train A started 2 hrs before B so it will travel 100 km

    Distance between Train A and Train B now = 450 – 100 = 350 km

    Train A increased speed 10km in 2 hrs so speed of Train B

    1st hr = 60 + 80 = 140km so balance 210 km

    2nd hr = 60 + 70 = 130 km balance 80

    = 70 + 60 = 130 so

    80/130 = 8/13

    Total hrs = 4 8/13 hrs

    Solutions

    x × 10000 + (x + 5) × 20000 = (2x + 5) × 16000

    So x = 10

    Total number of employees = 2x + 5 = 25
