If Jill loses 7 pounds, she will weigh half as much as her brother. Together, they now weigh 343 pounds. What is Jill’s present weight, in pounds?

(A) 107

(B) 119

(C) 127

(D) 133

(E) 143

We can let Jill’s current weight = j and her brother’s current weight = b.

j - 7 = (1/2)b

2j - 14 = b

and

j + b = 343

Substituting (2j - 14) for b in the equation j + b = 343, we have:

j + 2j - 14 = 343

3j = 357

j = 119

Answer: B
