Question

out of 3 numbers the ratio between 1st and 2nd number is 5:6 and the ratio between the 2nd and 3rd number is 15:16 if the difference between 1st and 3rd no is 700 find the average of all the numbers​

Answer 1

Answer:

2900

Step-by-step explanation:

5×5/6×5 equation 1

15×2/16×2 equation 2

equation 1

25:30

equation 2

30:32

therefore

1st no.=25x

2nd no.=30x

3rd no. =32x

according to question,

32x-25x=700

7x=700

x=100

putting the value of X

1st no. =25×100=2500

2nd no. =30×100=3000

3rd no. =32×100=3200

average of all numbers

=(2500+3000+3200)/3

=8700/3

=2900
