D. 5

View Answer	Favorite Question	Report

Answer: Option C

Explanation:

he average of the elements in the original set S is: (0 + 2 + 4 + 5 + 9)/5 = 20/5 = 4
If we remove an element that equals the average, then the average of the new set will remain unchanged. The new set after removing 4 is {0, 2, 5, 9}.
The average of the elements is, (0 + 2 + 5 + 9)/4 = 16/4 = 4

3880 . while working 7 hour a day , A alone can complete a piece of work in 6 days and B alone in 8 days . In what time would they complete it together , 8 hour a day?

A. 5 days
B. 3 days
C. 4 days
D. 3.6 days

View Answer	Favorite Question	Report

Answer: Option B

Explanation:

A can complete the work in 7*6 hrs = 42 hrs.
A can complete in 1 hr = 1/42 part.
B can complete the work in 7*8 hr = 56 hrs.
A&B together do in 1 hr = 1/42 + 1/56 = 7/168 = 1/24 part. So they will do in 8 hrs = 8*1/24 = 1/3 part.
Hence they need 1÷1/3 = 3 days to complete the work.

Answer: Option D

Explanation:

Mr. X 1 বছরের জন্য 10,000 টাকার একটি Deposit certificate কিনল, যা 6 মাস পর 8%

হার চক্রবৃদ্ধি সুদ প্রদান করে । Mr. X মোট কত টাকা সুদ পাবে তা বের করতে হবে ।

এখানে, সুদাসল, c = ?; semi annually হওয়ায়, n = 2; সময় t = 1 বছর; আসল, p = 10,000 Tk.

সুদের হার, r = 8% = 81008100

আমরাজানি, = P(1 + rn)n×tP(1 + rn)n×t

= > c = 100(1 + 82×100)2×1100(1 + 82×100)2×1

= > c = 10,000(1 + 125)210,000(1 + 125)2

= > c = 10,000(2625)210,000(2625)2

= > c = 10,000×26×2625×2510,000×26×2625×25

= > c = 10,816.

অর্থাৎ তিনি মোট সুদ পাবেন = (c - p) Tk.

= (10,816 - 10,000) Tk. = 816 টাকা ।
