1. We know the target for December is $310,000. We know March is 9 months earlier, but we don't know x. 2. We know X is$10,000 but have no starting point to find March with.

combined we know $310,000 is December Nov:$300,000
Oct: $290,000 Sep:$280,000
Aug: $270,000 July:$260,000
June: $250,000 May:$240,000
April: $230,000 March:$220,000

or you could just take $310,000 - ($10,000 * 9 months) = $220,000 Director Joined: 26 Jul 2007 Posts: 520 Schools: Stern, McCombs, Marshall, Wharton Re: For each month of next year, Company R's monthly revenue [#permalink] ### Show Tags 07 Dec 2007, 10:11 2 1 J=target revenue for January Stmt 1.

or you could just take $310,000 - ($10,000 * 9 months) = $220,000 Please help me understand how did we calculate x=10,000 from statement 2. It is an arithmetic progression: Let R be the revenue target for June. For July; revenue target=R+x For August; revenue target=R+2x For September; revenue target=R+3x (2) Company R's revenue target for September of next year is$30,000 greater than its revenue target for June of mext year.

$$R+3x-R=30000$$
$$x=10000$$-------------------------1
Not Sufficient.

(1) Company R's revenue target for December of next year is \$310,000

Let Jan's revenue target be J,

Common difference is "x". First term(January)=J; Last term or 12th term, say D(December)

$$A_n=A_1+(n-1)d$$

$$D=J+(n-1)x$$
$$D=J+(12-1)x$$

$$310000=J+11x$$-----2
Not Sufficient.

Using 1 and 2, we get J and we know x.

March Revenue Target= J+2x
Sufficient.

Ans: "C"

JAN FEB MAR APR MAY......... .DEC
a a+x a+2x a+11x

a+2x=?

1. Not Sufficient
a+11x = 310000

we dont know a or x. In other words different a , will give different x.

2. Not sufficient

a+8x = 30000 + a+5x

x can be found . But no info on a.

Together,

a+11x = 310000 and we have x from 2.

Hence this is Sufficient.

J (January), J + X, J +2X = ?
1) J + 11X = 310,000 Not sufficient.
2) J + 8X = J + 5X + 30,000 ; 3X = 30,000 ; X = 10,000
But do not know J, not sufficient
1) & 2) J + 11*10,000 = 310,000 ; J = 200,000 Done

Given: Monthly revenue target is x dollars greater than the target for the previous month
Required: Revenue for March of next year

Statement 1: Target for Dec = 310,000
Target for January = 310,000 + x
Target for February = 310,000 + 2x
Target for March = 310,000 = 3x

But we have no clue about x
INSUFFICIENT

Statement 2: Revenue for September - Revenue for June = 30,000
Hence 3x = 30,000
But we have no idea about the actual revenues.
INSUFFICIENT

Combining both statements:
We know the value of x and we know the value in one of the months,
Hence we can calculate the revenue in March
SUFFICIENT

Correct Option: C
