3.There are three numbers. 5 times the first and 6 times the second are equal. 3 times the second and 2 times the third are also equal. If the first number is 20 more than the third, find the third number. (a) 75 (b) 100 (c) 50 (d) 60 (e) 800​

Answer 1

Step-by-step explanation:

2)

Let the no.s be 9x,8x.

ATQ:

9x-14/8x-14 = 8/7

cross multiplying

63x-98=64x-112

x=14

So no.s are 9x=126,8x=112

3)

no.s be x,y,z

ATQ

5x=6y,3y=2z,x=20+z

5x=6y

5x=6*2/3z

5x=4z

x=4/5 z

x=20+z

4/5 z=20+z

z=-100

Answer 2

Answer:

2 = 36,32

3 = 60
