Answer 1

Answer:a) 15

Step-by-step explanation:

2÷3 x =4+6

So x =10×3÷2

x=15

b) let one numaber be x

Second no. x+8

Third no. x+16

According to the question

x+x+8+x+16=888

3x+24=888

3x=888-24

3x=864

x=288

C)let common ratio between the numbers be x

So 1st no. =4x

2nd no. =5x

ATQ

4x+5x=135

9x=135

x=135÷9
