Question

3. If 15% of x = 9, then x = ?​

Answer 1

Step-by-step explanation:

By hypothesis,

B+C

A

=

7

6

or 7A=6(B+C)

or 7A−6B−6C=0 ...... (i)

and

A+C

B

=

9

8

or 9B=8(A+C)

or 8A−9B+8C=0 ....... (ii)

Solving equations (i) and (ii) by cross multiplication, we get

−48−54

A

=

−48−56

b

=

−63+48

C

or

=102

A

=

−104

B

=

−15

C

or

102

A

=

104

B

=

15

C

∴ Sum of ratios =102+104+151=221

Hence, A, Band C's shares are respectively Rs.102,Rs.104 and Rs.15.
