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:
A20
B30
C48
D58
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.

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.
