Answer: Option A

Explanation:

the price per share at the end of the first year = 8.75 x (215 + 100)/100

the price per share at the end of the second year = 8.75 x (215 + 100)/100 x (100 - 40)/100

the price per share at the end of the third year = 8.75 x (215 + 100)/100 x (100 - 40)/100 x(100 - 20)/100

= 8.75 x 315/100 x 60/100 x 80/100

= 13.23 tk (ans)

A. 8
B. 16
C. 24
D. 12

View Answer	Favorite Question	Report

Answer: Option A

Explanation:

Let, the speed of Stream = x

,so, downstream speed = 16+x and upstream speed = 16-x

ATQ,

16+x = 3(16-x)

Or, 16+x = 48 -3x

Or, 4x = 32

Or, x =8

So speed of stream = 8 and difference of speed of still water & stream = 16–8 = 8km/hr

ধরি, মোট টাকার পরিমাণ x

আনুপাতিক রাশিগুলোর যোগফল = 2 + 3 + 7 = 12

সাইফের অংশ = x এর 2/12

= x/6

ডা. নাজমার অংশ = x এর 3/12

= x/4

শাকিলের অংশ = x এর 7/12

= 7x/12

প্রশ্নমতে, 7x/12 - ( x/6 + x/4) = 1500

= > 7x/12 - 5x/12 = 1500

= > 2x/12 = 1500

= > x/6 = 1500

= > x = 9000

মোট টাকার পরিমাণ 9000 টাকা৷

সাইফের অংশ = x/6 = 9000/6 = 1500 টাকা (উওর

Let the ages of Kunal and Sugar 6 years ago be 6x and 5x years respectively.
Then, {(6x + 6) + 4}/{(5x + 6) + 4} = 11/10
⇒10(6x + 10) = 11(5x + 10)
⇒5x = 10
⇒x = 1
∴ Sagar's present age = (5x + 6) = 16 years.
