1. If x, y, z are chosen from the three numbers -3, 1/2 and 2, what is the largest possible value of the expression (x/y) z২?
- A. 16
- B. 16
- C. 16
- D. 16
Answer: Option C
Explanation:
Here, the rest is=(100-45+30)%=25%
People who contributed with 2 taka=(300/2)=150
Now,
25% means 150
So, 30% means (150×30)/25=180 people
So, 45% means (150×45)/25=270 people
Total contributed
=300+(180×40)+(270×20)
=12900 taka
(ans).
