In a factory, there are equal number of men and children. Men work 9 hours a day and children work 6 hours a day. In festive season, the work load goes up by 60%. Due to restriction on children, they can only work 6 hours a day. So the extra work is done by men. If the men and children are equally efficient, then what extra work hours are out on men every day?

  1. 7 hours
  2. 9 hours
  3. 5 hours
  4. 6 hours
  5. None of these

Option 2 : 9 hours

As we know, if M1 men can do W1 work in D1 days working for H1 hours per day and M2 men can do W2 work in D2 days working for H2 hours per day at the same efficiency, then,

⇒ (M1 × D1 × H1)/W1 = (M2 × D2 × H2)/W2

Let extra hours of work per day be ‘x’ hours

Let work done on normal days be ‘100 units’

Work done in festive season = (100 + 60)% of 100 = 160 units

∵ Men and children are equally efficient and there number remains the same, hence we can write, for 1 day work,

⇒ /100 = /160

⇒ 15/100 = (15 + x)/160

⇒ 15 + x = 24

⇒ x = 24 - 15 = 9 hours

∴ Extra work of 9 hours is to be done

9 men can finish a work in 12 days working 4 hours in a day and 12 children can finish the same work in 6 days working ‘x’ hours a day. What is the value of ‘x’ if a man is 1.5 times as efficient as of a boy?

Option 3 : 9 hoursThe ratio of efficiency of a man to a boy = 1.5 : 1 = 3 : 2 3 children = 2 men 12 children = 8 men Now, MDH...

A house has a number which needs to be identified. The following three statements are given that can help in identifying the house number. If the house number is a multiple of 3, then it is a number from 50 to 59. If the house number is NOT a multiple of 4, then it is a number from 60 to 69. If the house number is NOT a multiple of 6, then it is a number from 70 to 79. What is the house number?

Option 4 : 76 Condition 1: If the house number is a multiple of 3, then it is a number from 50 to 59. Possibilities: 51, 54, 57 But if one of these is the...

Kalyani started her walk from point T towards East,and went straight to the point U which is 4 feet away. She turns left, at 90° and walks to the point W which is 4 feet away, and then she turns 90° right and goes to 3 feet to the point P. Then she turns 90° right and walks 1 feet to point Q. Then she turns left 90° and goes to point V, which is 1 feet away and once again she turns 90° right and goes to point O, which is 3 feet away. What is the distance between T and O?

Given below are two quantities named A and B. Based on the given information, you have to determine the relation between the two quantities. You should use the given data and your knowledge of Mathematics to choose between the possible answers. Quantity A : 10 men and 15 women can complete a piece of work in 15 days while 5men and 10 women can complete the work in 25 days. What part of work a woman can complete in 1 day Quantity B : 5 women and 10 girls can complete stitching work in 10 days and 7 women and 5 girls can complete this same work in 15 days. What fraction of work remains if 6 girls work alone for 6 days?

Option 2 : Quantity A < Quantity BQuantity A: Let 1 men’s 1 day’s work = x and 1 women’s 1 day’s work = y Then, 10x + 15y = 1/15 5x + 10y...

Given below are two quantities named 1 and 2. Based on the given information, you have to determine the relationship between the two quantities. You should use the given data and your knowledge of Mathematics to choose between the possible answers. Quantity 1: P and Q can do a work in 6 days and Q and R can do a work in 60/7 days and P and R can do a work in 20/3 days. If Q and R work for first 2 days and left the work. Find the total time taken by P to complete the remaining work. Quantity 2: A and B can do a work in 8/3 days, B and C can do the same work in 3 days and A and C can do the same work in 24/5 days. In what time C alone can complete the work?

Option 2 : Quantity 1 < Quantity 2Quantity 1: Given, P and Q together can complete the work in = 6 days Q and R together can complete the work in = 60/7...

Compare the values of the two quantities in the question and answer. Quantity 1: If A can do a piece of work in 15 days and B is half as efficient as A, then what percentage of the work will they both do together in 8 days Quantity 2: If A is twice as efficient as B and they both can do a piece of work in 12 days, then what percentage of the work will B do alone in 20 days?

Option 1 : Quantity 1 > Quantity 2Solving for Quantity 1: A’s 1 day work = 1/15 B’s 1 day work = ½ × 1/15 = 1/30 (A + B) ’s 1 day...

There are two rows, each containing 3 numbers. Some rules are given below to be used for obtaining the resultant number for each row separately. Apply the rules for each row from left to right and answer the question. Rules: i. If an even number is followed by an even number, the first is to be subtracted from the second. ii. If an odd number is followed by an odd number, both are to be added. iii. If an odd number is followed by an even number, the even number is to be subtracted from the square of the odd number. iv. If an even number is followed by an odd number, the odd number is to be subtracted from the even number. Row I: 28, 19, 12 Row II: 13, 7, 32 What is the average of the resultant numbers of the first row and the second row?

Option 3 : 40.5Given Rows  Row I: 28, 19, 12 Row II: 13, 7, 32 Using the above rules The Row 1 can be  Row I: 28, 19, 12, From left to right the even number...
