If `a : b=2:5,` . fid the value of `(3a+2b)/(4a+b)`

If a : b=2:5, . find the value of (3a+2b)/(4a+b)

If a:b = 2:5, the find the value of ((3a + 2b))/((4a + b)) .

If a=3, b=4, c=5, find the value of tan( B/2) .

If a/b=2/3 then find the values of (4a+3b)/(3b)

If (2a+b)/(a +4b)=3 , then find the value of (a+b)/(a+2b)

If a : b = 3 :sqrt5 , then the value of (2a + b) : (3a - 2b) is: यदि a : b = 3 :sqrt5 , तो (2a + b): (3a -2b) का मान है:

If a/b=4/3, then what is the value of (3a+2b)div(a-b) ?

If (2a+ b)/(a+4b) = 3 , then find the value of (a+b)/(a+2b)
