a. 1 : 2
b. 2 : 1
c. 1 : 1
d. None of these
e. Cannot be determined

ANSWER: 2 : 1
 
After spending Rs. 125 (25 * 5) for articles of type C, the housewife is left with Rs. 75 (200 – 125). Since this amount has to be spent in totality, she must have purchased 2 articles of type A (equivalent to Rs. 40) and 1 article of type B (equivalent to Rs. 35). Thus, the required ratio is 2 : 1.
