Q2

Length of rectangular park = 175 m

Breadth of rectangular park = 125 m

Perimeter of park = 2 x (length + breadth)

= 2 × (175 + 125)

= 2 × 300 = 600 m

Since, cost of fencing park per meter = Rs. 12

Therefore, cost of fencing park of 600 m = 12 × 600 = Rs. 7,200

Q3

n+12=20

n=20-12

n=8

Q4

33 : 44 = 33/44 = 3/4 = 3 : 4

75 : 100 = 75/100 = 3/4 = 3 : 4

Since 33 : 44 = 75 : 100

∴ 33, 44, 75, 100 are in ratio
