Question 1 of 10
1. Question
To do a certain work Livingston is 100/3% more efficient than Raju. They started to work alternatively on the same work starting from Livingston on first day and Raju on second day and finished 50% of the work in 40 days. Find the time taken by Livingston alone to complete the work.
Correct
Answer: a)
Ratio of efficiency of Livingston and Raju= 4:3
Then work done by Livingston= 4x units and work done by Raju=3x units
Since, 50% of the work completed in 40 days, 100% of the work will be completed in 80 days.
If they both work together, 7x units will be completed in two days.
So in 80 days, 80/2*7x units will be completed.
Hence the whole work will be completed by Livingston= (80*7x)/(2*4x)
= 70 days.

2. Question
7 typists working 8 hours a day can type a book in 20 days. How many days will 4 typists take to do the same job, each working 7 hours a day?
Correct
Answer: c)
Let the number of days be x.
Then 7*8*20=4*7*x
x= 40 days
Incorrect
Answer: c)
Let the number of days be x.
Then 7*8*20=4*7*x
x= 40 days

A person invests Rs 40000 in two different parts, one at 10% per annum simple interest and the other at 20% per annum compound interest. If at the end of two years he gets a total interest of Rs 8580, then what amount did he invest under compound interest (approximately)?

Marked price of an article is Rs 2600 more than the cost price. When the same article is sold at a discount of Rs 1000 then the percentage profit earned is 20%. For earning a profit of 25, the article should be sold at what price?
Correct
Answer: a)
Given that Marked price- Cost price= Rs 2600
Then 2600= profit + discount
Thus profit= 2600-1000= 1600
(i.e.) 20% of the profit= Rs 1600
Then 25% of the profit= (1600/20)*25
= Rs 2000
Incorrect
Answer: a)
Given that Marked price- Cost price= Rs 2600
Then 2600= profit + discount
Thus profit= 2600-1000= 1600
(i.e.) 20% of the profit= Rs 1600
Then 25% of the profit= (1600/20)*25
= Rs 2000

Answers :
Direction (1-5) :
1) Answer: a)
Ratio of efficiency of Livingston and Raju= 4:3
Then work done by Livingston= 4x units and work done by Raju=3x units
Since, 50% of the work completed in 40 days, 100% of the work will be completed in 80 days.
If they both work together, 7x units will be completed in two days.
So in 80 days, 80/2*7x units will be completed.
Hence the whole work will be completed by Livingston= (80*7x)/(2*4x)
