Answer:
1.26(9+26) is the answer for 1st question
Answer:
(1). Let the number be x.
ATQ,
x + 9 = 35
x = 35 - 9
x = 26 Ans.
(2). Let the number be x.
ATQ,
3x - 6 = 21
3x = 21 + 6
3x = 27
x = 27/3
x = 9 Ans.
(3). Let the number be x.
ATQ,
x/5 = 12
x = 12 × 5
x = 60 Ans.
(4). Let the numbers be x , x + 2, x + 4
ATQ,
x + x + 2 + x + 4 = 60
3x + 6 = 60
3x = 60 - 6
3x = 54
x = 54/3
x = 18
x + 2 = 18 + 2 = 20
x + 4 = 18 + 4 = 22
So, the three consecutive positive even integers are 18 , 20 , 22.
(5). Let the numbers be x + 1 , x + 3.
ATQ,
x + 1 + x + 3 = 72
2x + 4 = 72
2x = 72 - 4
2x = 68
x = 68/2
x = 34
x + 1 = 34 + 1 = 35
x + 3 = 34 + 3 = 37
So, the two consecutive odd integers are 35, 37.
(6). Let the number be x.
ATQ,
2x - 11 = 15
2x = 15 + 11
2x = 26
x = 26/2
x = 13 Ans.
(7). Let the number be x.
ATQ,
3x/4 = 30
3x = 30 × 4
3x = 120
x = 120/3
x = 40 Ans.
