(B) $15 (C)$20

(D) $40 (E)$50

Solution

• Initial Amount with Betty $$= 60$$

• Amount spent at the supermarket $$= \frac{1}{3} *$$ Initial Amount $$= \frac{1}{3}* 60 = 20$$

o Amount Left $$=  (60-20) = 40$$

• Amount Spent at the drugstore $$= \frac{1}{2} *$$ Amount Left $$= \frac{1}{2} * 40 = 20$$

• Since she did not do any other shopping. The amount she had when she returned home = Amount Left after spending in supermarket – Amount Spent at Drugstore $$=  (40 – 20) = 20$$.

Correct Answer : Option C.
