How many gift boxes were sold on Monday ?
Statements:
I. It was 10% more than the boxes sold on the earlier day i.e., Sunday.

B. II alone is sufficient while I alone is not sufficient

C. Either I or II is sufficient

D. Neither I nor II is sufficient

E. Both I and II are sufficient

Answer : E. Both I and II are sufficient

From II, we can conclude (1500/3) i.e., 500 boxes were sold on Sunday.
From I, we find that number of boxes sold on Monday = 500 + 10% of 500 = 550.

Vipin’s and Javed’s salaries are in the proportion of 4:3 respectively. What is Vipin’s salary ?
Statements :
I. Javed’s salary is 75% that of Vipin’s salary.
II. Javed’s salary is Rs.4500.

A. I alone is sufficient while II alone is not sufficient

B. II alone is sufficient while I alone is not sufficient

C. Either I or II is sufficient

D. Neither I nor II is sufficient

E. Both I and II are sufficient

Answer : B. II alone is sufficient while I alone is not sufficient

Explanation:

Vipin’s salary can be determined from statement II as follows:
Let Vipin’s and Javed’s salaries be 4x and 3x respectively.
Then, 3x = 4500 or x = 1500.
Vipin’s salary = 4x = Rs.6000.
Thus, II alone is sufficient
