" If "(a)/(3)=(b)/(4)=(c)/(7)," then "(a+b+c)/(c)=?

If (a)/(3)=(b)/(4)=(c)/(7) find (a+b+c)/(c)

If (a)/(3)=(b)/(4)=(c)/(7), the value of (a+b+c)-:c is (a) (1)/(7)(b)(1)/(2)(c)2(d)7

If (a)/(b)=(4)/(5) and (b)/(c)=(15)/(16), then (c^(2)-a^(2))/(c^(2)+a^(2)) is (a) (1)/(7)( b) (7)/(25)( c) (3)/(4) (d) None of these

If (a)/(b)=(4)/(5)and(b)/(c)=(15)/(16) then (c^(2)-a^(2))/(c^(2)+a^(2)) would be (1)/(7) b.(3)/(4) c.(7)/(25) d.none of these

a//3=b//4=c//7 then find (a+b+c)//c .

If (b+c)/(5)=(c+a)/(6)=(a+b)/(7) then sin A:sin B:sin C=4:3:2

If a :b::3:4 & b:c:: 4:7. then (a +b + c)/( c ) = ?
