Answer 2

Step-by-step explanation:

Ans.13

Required - A number which when multiplied by 9 is increased by 72.

Let the number be x.

ATQ ,

x × 9 = x + 72

9x = x + 72

9x - x = 72

8x = 72

x = 72 / 8

x = 9

So, Required number is 9.

Ans 14.

Required - Two numbers in which one no. is greater by 4 the other and their sum is 28.

Let the two numbers be x and y.

ATQ,

x + y = 28

Also, y = x + 4

Substituting the value of y

x + x + 4 = 28

2x = 28 -4

x = 24 /2

x = 12

So, y = 12 + 4 = 16

The two numbes are 12 and 16.

Ans 15.

Required - when 20 is subtracted from twice a number , the answer is 100

Let the number be x .

ATQ ,

2x - 20 = 100

2x = 100 + 20

x = 120 /2

x = 60

Ans....

Hope this helps :)
