A sum of money is to be distributed among A, B, C, D in the proportion of 5 : 2 : 4 : 3. If C gets Rs. 1000 more than D, what is B's share?


ARs. 500

BRs. 1500

CRs. 2000

DNone of these

Answer: Option C

Explanation:

Let the shares of A, B, C and D be Rs. 5x, Rs. 2x, Rs. 4x and Rs. 3x respectively.



Then 4x - 3x = 1000



x = 1000.



So B's share = Rs. 2x = Rs. (2 x 1000) = Rs. 2000.

The sum of three numbers is 98. If the ratio of the first to second is 2 :3 and that of the second to the third is 5 : 8, then the second number is:

D58

 View Answer |  Discuss in Forum |  Workspace | Asked In nagarroGlobal Edge |

Answer: Option C

Explanation:

Let the three parts be A, B, C. Then,

A : B = 2 : 3 and B : C = 5 : 8 = 5 * 3/5 : 8 * 3/5 = 3 : 24/5

=> A : B : C = 2 : 3 : 24/5 = 10 : 15 : 24

=> B = 98 x 15/49 = 30.

Three sales people are paid commissions in proportion to the amount of their sales, which total $25000, $40000, and $60000 respectively. If a total of $20000 is allocated for these three commissions, what is the amount of the largest commission paid?


A$6,400

B$8,400

C$9,600

D$12,000

Answer: Option C

Explanation:

The proportion of their commission = 25000:40000:60000
=> 5:8:12
So the largest commission =(12/25)*20000 = $9600.

Two boys begin together to write out a booklet containing 535 lines. The first boy starts with the first line, writing at the rate of 100 lines an hour; and the second starts with the last line then writes line 534 and so on, backward proceeding at the rate of 50 lines an hour. At what line will they meet?


A57th line

B375th line

C357th line

D380th line

Answer: Option C

Explanation:

Writing ratio = 100:50= 2:1
Since equal quantities are taken,
Therefore in a given time, first boy will be writing the line number
2/3 * 535
=> 356 2/3 or 357th line.
Hence, both of them shall meet on 357th line.

Three men rent a farm for Rs. 7000 per annum. A puts 110 cows in the farm for 3 months, B puts 110 cows for 6 months and C puts 440 cows for 3 months. What percentage of the total expenditure should A pay?


A20%

B14.28%

C16.66%

D11.01%

Answer: Option B

Explanation:

A:B:C=110*3:110*6:440*3 = 3:6:12 = 1:2:4

share of A = 1/(1+2+4) * 7000 = 1000

% expenditure of A = 1000/7000 *100 = 100/7 = 14.28%
