A. 8
B. 16
C. 24

View Answer	Favorite Question

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

Explanation:

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
