Q1 . A,B and C start a business by investing Rs 6000 each in the business.After 6 months they add 2000 ,3000 and 5000 to the intial amounts.The total profit obtained at the end of the year is 75000.Find the share of C?
Q2 . Let us assume that A and B have their working effeciency in the ratio 2:3.They work on a project on alternate days for a month(30 days) by starting with A and ending with B.what is the ratio in which they will spit their wages?
1. 3:4
2. 3:5
3. 3:2
4. 1:2
Correct Answer is
3:2
SOLUTION
so the time taken is inverse of work effeciency 3:2
so let us consider them as hours a day
so A would have worked for 15x3 and B for 15x2
45 and 30 hours respectively
so wages will be split in the ratio 3:2
Q3 . If A and B invest money in the ratio 5:4.After 6 months,they withdraw 2/5 and 3/4 of the money from the intial investment.After a year the total profit is 130000.what is As share?
1. Rs 80000
2. Rs 85000
3. Rs 82000
4. Rs 75000
Correct Answer is
Rs 80000
SOLUTION
let the money invested be 5k and 4k
5k x 6+ ((5k-2/5(5k)) x 6):4k x 6+ ((4k-3/4(4k)) x 6)
48k:30k
8:5
As share is 8/13x130000
Rs 80000
Q4 . A and B work for 10 hours and 12 hours per day for 12 and 10 days respectively to complete a piece of work.The total amount of money recieved for the project is 48000.find the As share of money?
1. Rs 27000
2. Rs 25000
3. Rs 20000
4. Rs 24000
Correct Answer is
Rs 24000
SOLUTION
to find the amount of work done by A:B
10x12:12:10
120:120
The work done is equal
As share is half of 48000
Rs 24000
Q5 . If A and B have a working effeciency of 5:4 and they work for 10 days by both of them working for equal no of hours a day.The total money recieved is 90000 find Bs share?
1. Rs 55000
2. Rs 50000
3. Rs 45000
4. Rs 25000
Correct Answer is
Rs 50000
SOLUTION
since A and B have effeciencies in ratio 5:4 time taken will be in ratio 4:5
