Question

9000 were divided among X Y and Z in the ratio 1/28 : 1/7:1/4 , i) Share of X is (A) 750 (B) 1800 (C) 2150 (D) 2200 , ii)The share of Y is (A) 750 (B)3000 (C) 5250 (D)5400 ,iii) The share of Z is: (A) 4000 (B) 5200 (C) 5175 (D) 5250 ​

Answer 1

Answer:

Share of X is $=750$

Share of Y is $=3000$

Share of Z is $=5250$

Step-by-step explanation:

The sum $9000$ is divided in to $\frac{1}{28} +\frac{1}{7} +\frac{1}{4}$ parts.

that is $\frac{1}{28}+\frac{1}{7}+\frac{1}4}=\frac{1}{28}+ \frac{4}{28}+ \frac{7}{28}$

                            $=\frac{12}{28}$ parts.

Hence share of A is

$9000(\frac{1}{28} /\frac{12}{28} )=9000(\frac{1}{28}*\frac{28}{12} )=\frac{9000}{12} =750$

similarly, share of B is

$9000(\frac{4}{28}/\frac{12}{28} )=9000(\frac{4}{12} )=3000$

and, share of C is

$9000(\frac{7}{28} /\frac{12}{28} )=9000(\frac{7}{12} )=5250$

Hence the answer
