Answers:
A) 19:49:64  B) 20:49:64  C) 20:49:65  D) 20:50:64  E) None of these
Explanation:   Let their investments be Rs. x for 14 months, Rs. y for 8 months and Rs. z for 7 months respectively   Then, 14x : 8y : 7z = 5 : 7 : 8   Now, 14x/8x = 5/7   =&gt; y = (49/20)x   14x/7z = 5/8   =&gt; z = (16/5)x   =&gt;x:y:z = x:(49/20)x:(16/5)x   = 20:49:64   Option 20:49:64
