Question

Given h : k = 4 : 3 and the sum of h and k is 21. Find h

Answer 1

Let h and k be 4x and 3x respectively

so
4x + 3x = 21
7x = 21
x =3


So value of h = 4x = 12

Answer 2

As it is given that h and k are in the ratio of 4:3 respectively and their sum is 21 .

So let h be 4x and k be 3x ....

= 4x + 3x = 21
= 7x = 21
= x =21/7
so,x=3....and we know that h is 4x
h=4(3)
h=12
