A Tk. 4000
B TK. 4600
C TK. 32oo
D TK. 3600

Correct Answer: Tk. 4000

Let, Principle = x Interest of 5% x of 5% = x ×5100 = 5x100 = x20Interest of 6%,x of 6%  = x×6100 = 3x50Interest of 8% , x of 8%  =  x ×8100 = 3x50Interest of 8% , x of 8% =  x×8100 = 2x25ATQ,x20 + 3x50 + 2x25 = 760⇒5x + 6x + 8x100 = 760⇒19x  = 760×100⇒x = 760×10019.'. x  = 4000
