Why my solution is incorrect?
Zigfield bought his car using M% of his bank savings. He also bought a house that costs 4 times the price of the car. What is the price of the house?
(1) M = 12.
(2) The price of the car and the house was $140,000.
The best answer is C.
With statement (1) we know that the car cost 12% of his life savings.
From statement (1) and (2) we know that (12 x 4 = 48) percent of his life savings went to the house. 60% of his life savings is $140,000. From here we know how much were his life savings and so we know that 48% of that went to the house. Both statements are needed.
I think
(1) is insuffucient
(2) I got -- Car+House = 140000 (eq1),
and from the question I can got House = 4*Car (eq2)
from (2) I can solve for C and H
What's wrong????
