Two number are in the ratio 7 : 3 if their difference is 20 find the number |
Answer» here, if X and y are in the RATIO of 7:3 , and they have difference of 20 between them,x - y = 20 ;and that would make x/y = 7/3 ;i.e. x = 7y/3 ,TAKING that value of x , and putting it into first equation will give us,7y/3 - y = 20;so, 7y - 3y = 60 ;that is, 4Y = 60 ;and that will give us, y = 15 . and so on, x = 35 ;So the answer is, 35 and 15 are the numbers that are in the ratio 0F 7:3 and have difference of 20. |
