Question

three numbers are in the ratio 4 :5 :6 if each is increased by 10 the ratio between the New numbers from 5:7 find the original number explanation ​

Answer 1

Step-by-step explanation:

n:n': n" = 4:5:6 (given)

n=4x+10

n' = 5x+10

n" = 6x + 10

5/7=4x+10/5x+10

=> 25x+50 = 28x + 70

=> 3X = -20

=> x = -20 / 3

=> x = - 6.66

n=4x (-6.66) + 10 = -26.64 +10=-16.64

n' = 5x (-6.66) +10=-33.3 +10= -23.33

n" = 6x (-6.66)+10=-59.94+10= -49.94
