QUESTION: 8

Size of a tile is 9 inches by 9 inches. The number of tiles needed to cover a floor of 12 feet by 12 feet is

Solution:

QUESTION: 9

Area of a square field is 1 hectare. The length of another square field is 1% more than the length of this square field. The difference in their areas is

Solution:

1 hectare = 10000 m2
Area of a square field = 10000 m2
let length of a square field be x m
then x2 = 10000
x = 100m
length of other square field = 100 + 100 x 1/100 = 101
Area of Another square field = (101)2 = 10201 m2
∴ Difference in their areas = 10201 - 10000
= 201 m2

QUESTION: 10

The average of three numbers is 135. The largest number is 180 and the difference of the others is 25. The smallest number is

Solution:



⇒ x + y + z = 405
But let x = largest number i.e. 180
⇒ y + z = 225 .....(1)
Also, y - z = 25 .....(2)
Solving (1) and (2)
We get 2y = 250
⇒ y = 125
⇒ z = 125 - 25 = 100
Hence, the smallest number among the three numbers is 100

QUESTION: 11
The equation of the straight line which is perpendicular to y = x and passes through (3, 2) is :

⇒ λ = -5
⇒ x + y = 5
