1816 . If 2 < x < 4 and 3 < y < 7, what is the largest integer value of x + y?

A. 9
B. 10
C. 7
D. 8

View Answer	Favorite Question	Report

Answer: Option B

Explanation:

x is less than 4 and y is less than 7. That means that if only the value of x+y is restricted to being an integer, x could be 3.5 and y could be 6.5, and so x+y=10. Since x+y cannot be 11, 10 is the largest integral value.

A. 13 : 42
B. 19 : 43

D. 17 : 43

View Answer	Favorite Question	Report

Answer: Option D

Explanation:

In 1st metal,

Zinc = 2×(1/3) = 2/3

Copper = 2×(2/3) = (4/3)

In 2nd metal,

Zinc = 3×(1/4) = (3/4)

Copper = 3×(3/4) = (9/4)

New ratio , Zinc : Copper = {(2/3) + (3/4)} :{(4/3) + (9/4)}

= {(8 + 9)/12}:{(16 + 27)/12}

= (17/12):(43/12)

= 17:43 (Ans)
