Q.1

Let three consecutive integer is x-1 , x ,x+1 .

so ,

2(x-1)+3x+4(x+1) = 56

2x-2+3x+4x+4 = 56

9x =56-4+2

so , x= 54/9 = 6

there integer are (6-1) = 5 , 6, (6+1)=7

Q.2

let length & breadth of the plot is 11x & 4x respectively .

total length of fence become 2(11x+4x) = 30x

so , 100× 30x = 75000

so , x = 75000/3000 =25

so length = 11×25 = 275 m

breadth= 11×4 = 44 m

Q.3

let the number is x

(x-5/2)×8 = 3x

8x- 20= 3x

x = 20/5 = 4
